“Just to make sure that he’s ready to go before we let him back out there,” Arians said.
Arians said Jefferson would see the team's independent neurological consultant Friday as a precaution.
After Friday’s practice, Arians said Jefferson was feeling fine and was joking around in the locker room.
On Thursday, Jefferson said he didn’t remember much, if any, of last Sunday's game against Philadelphia. He thought he suffered the concussion during a kickoff, but couldn’t recall the exact moment.
He started showing symptoms Sunday night and was diagnosed with the concussion Monday morning, Arians said.
If Jefferson can’t play Sunday, second-year safety Tyrann Mathieu will fill his role in base coverage and rookie safety Deone Bucannon will get more snaps, Arians said.
Cornerback Patrick Peterson, who also suffered a concussion in Sunday’s game, was listed as probable for Sunday's game.
Second-year running back Stepfan Taylor (calf) will not play. Rookie tight end Troy Niklas (ankle) was listed as questionable.
Also listed as probable were defensive end Calais Campbell (knee), linebacker Kenny Demens (knee), running back Andre Ellington (foot), wide receiver Michael Floyd (knee) and safety Rashad Johnson (knee).
No players were ruled out for Sunday's home game against the St. Louis Rams, and while there are questions about the availabilty of All-Pro inside linebacker Patrick Willis because of a sprained toe, the Niners are as healthy as they’ve been since early September.
Willis and cornerback Tramaine Brock (toe) were both limited in Friday’s practice. Cornerback Chris Culliver (hamstring) and safety Jimmie Ward were full participants.
Following is the 49ers’ status report for Sunday’s game against the Rams:
Questionable: CB Tramaine Brock (toe), LB Patrick Willis (toe)
Probable: CB Chris Culliver (hamstring), S Jimmie Ward (quadricep)
Starting left tackle Russell Okung and starting strong safety Kam Chancellor will be game-time decisions, Seahawks coach Pete Carroll said Friday after practice.
"Max made it through the week, so that’s a real good sign," Carroll said. "It will be nice to have him back out there."
Unger told reporters he’s healthy, but when Carroll was asked if Unger will start, he didn’t answer.
Carroll said backup center Stephen Schilling, who has a knee injury, will dress for the game. Schilling started the past three games while Unger has been out. It is likely third-string center Patrick Lewis will be active for the game.
Okung had practiced all week until Friday when a calf injury popped up. He has been playing all season with a sprained left shoulder that has a labrum tear. If Okung is out, Alvin Bailey is the likely starter a left tackle.
Chancellor now has a groin injury that makes him questionable for the game. He has been playing with ankle problems and a hip issue after having offseason hip surgery.
The Seahawks are thin at safety if Chancellor can’t play. DeShawn Shead would start because backup Jeron Johnson did not make it through the concussion protocol this week. The only other backup safety is Steven Terrell, so the Seahawks might make a roster move on Saturday to add a defensive back.
Starting cornerback Byron Maxwell will miss his third consecutive game because of a calf injury. Tharold Simon will start again for Maxwell. Simon returned to practice Friday after missing Thursday's practice with a sore knee.
Also out for Sunday are outside linebacker Malcolm Smith (groin), tight end Zach Miller (ankle), middle linebacker Bobby Wagner (turf toe) and defensive tackle Jordan Hill (ankle).
Cornerback Richard Sherman (knee) and defensive end Michael Bennett (toe) were full participants in practice after resting on Thursday. Carroll said both players are fine.
Another bit of positive news is newly acquired fullback Will Tukuafu, the 285-pound former San Francisco 49er, will play fullback Sunday. Tukuafu has played most of his career as a defensive end.
"Will was really impressive this week," Carroll said. "He has way more experience playing the [fullback] position than we thought. He showed an ability to pick stuff up real quick, and when he’s laying into someone at 280 [pounds], there’s a difference at that spot and exciting to see. He’s going to be playing and we’re anxious to see what he can do."
Jones did not play in the Patriots’ victory over the Chicago Bears last Sunday. There have been reports that Jones will miss significant time with a hip injury.
Elsewhere on the health front, linebacker Dont’a Hightower was removed from the injury report. Hightower was dealing with a knee injury that kept him out of the team’s Oct. 12 victory over Buffalo. With linebacker Jerod Mayo out for the season, Hightower has filled Mayo’s role. Hightower at 100 percent again is a boost for the defense.
Veteran defensive lineman Alan Branch was also removed from the injury report after appearing on it for a non-injury-related reason on Thursday. Branch is expected to play Sunday to provide depth for the defensive front against the run.
Rookie defensive lineman Dominique Easley (knee), rookie offensive lineman Cameron Fleming (finger), and core special-teamers Nate Ebner (finger) and Matthew Slater (shoulder) are questionable for Sunday’s game.
Quarterback Tom Brady (ankle) and cornerback Brandon Browner (ankle) are listed as probable.
Meanwhile, receiver Kenbrell Thompkins returned to pratice Friday. He missed Thursday’s workout for a personal reason. He is expected to play Sunday.
As expected, tight end David Ausberry (foot), wide receiver Vincent Brown (hamstring), cornerback Chimdi Chekwa (hamstring) and cornerback Keith McGill (groin) have been ruled out for Sunday's game.
Meanwhile, Oakland safety Brandian Ross was fined $22,050 for unnecessary roughness (striking a defenseless receiver in head and neck area) for a hit on Cleveland tight end Jordan Cameron in Week 8. Ross makes an average of just over $35,000 a game. Thus, the starter was docked roughly 63 percent of his pay for the week. Ross was penalized on the play.
Here is the rest of the injury report:
Doubtful: CB Darrin Walls (calf/knee).
Questonable: QB Smith (right shoulder).
Probable: OL Oday Aboushi (shoulder), LB Antwan Barnes (knee), OL Willie Colon (knee), TE Jeff Cumberland (shoulder/finger), LB Demario Davis (finger), WR Eric Decker (hamstring), LB David Harris (shoulder), RB Chris Johnson (ankle), WR Jeremy Kerley (illness), OL Nick Mangold (shoulder), LB Trevor Reilly (knee), WR Greg Salas (wrist/ankle).
Out: WR Donnie Avery (groin), CB Jamell Fleming (hamstring), LB Josh Martin (hamstring), CB Chris Owens (knee).
Probable: S Eric Berry (ankle), TE Travis Kelce (ribs), RB Jamaal Charles (back), TE Anthony Fasano (shoulder), CB Phillip Gaines (quad), WR Junior Hemingway (hamstring), OL Mike McGlynn (foot), QB Alex Smith (right shoulder), CB Sean Smith (groin), RB Cyrus Gray (hand).
Rodgers-Cromartie has been dealing with leg and back problems for more than a month, and wasn't able to play in much of the team's Week 7 loss in Dallas. He's been getting treatment through the bye week, but his health issues obviously haven't cleared all the way up, and head coach Tom Coughlin said "I don't believe we can do that at this point" when asked about counting on Rodgers-Cromartie being able to play the whole game.
Colts quarterback Andrew Luck leads the league in passing yardage, so he obviously poses a serious challenge to a Giants secondary that is already without nickel cornerbacks Walter Thurmond and Trumaine McBride. A limited Rodgers-Cromartie is a potentially big problem in a game like this.
On the offensive side of the ball, Coughlin called guard Geoff Schwartz "a long shot" to return from injured reserve this week. Schwartz just started practicing this week on the toe injury that's kept him out since training camp, and they still have 17 more days before they are required to activate him.
And running back Rashad Jennings, who has already been ruled out of a third straight game with his knee injury, said he's still a few days from trying to move laterally on his leg, and that Week 11's game against the 49ers is a more realistic goal than the Week 10 game in Seattle, though he wouldn't rule that out.
Gruden said during his news conference that the injury was not serious. Later, during his weekly appearance on ESPN980, Gruden said Breeland had the knee checked out and that "it looks like it’ll be OK." Gruden called it a sprain and said they will find out more Saturday. They want to make sure it doesn’t swell overnight.
The injury occurred late in practice when Breeland’s foot got caught in the grass.
If Breeland can’t play, then the Redskins could turn to veteran Tracy Porter or second-year player Chase Minnifield.
"We have other guys, but obviously we want Breeland," Gruden said.
"Being able to run again is encouraging," Mathews told the Associated Press. "That's a big step. I'm very encouraged. The trainers are doing a great job and I'm just following their plan. Every time they put me through something I'm just trying to do my best."
Mathews was a limited participant but has been ruled out for Sunday's contest on the road against the Miami Dolphins. He's hopeful to play against the Oakland Raiders on Nov. 16 after San Diego's bye week.
"It's great to have him out there," Chargers coach Mike McCoy said about Mathews. "He's worked extremely hard, fighting through a tough injury early on. He's done everything he can. So he's getting close. He's taking it one day at a time. And it's great to have him run around out there."
Here is a look at the final injury report for Miami:
Out: TE Dion Sims (toe)
Questionable: G Daryn Colledge (illness, back), LB Koa Misi (ankle)
Probable: TE Charles Clay (knee), LS John Denney (knee), CB Cortland Finnegan (neck), G Nate Garner (neck), LB Chris McCain (foot), C Mike Pouncey (hip), S Jimmy Wilson (hamstring)
Analysis: The Dolphins are very healthy to enter the midpoint of the season. Sims, Miami's backup tight end, will miss his first game of the season. Rookie Gator Hoskins will take some reps behind starting tight end Clay on Sunday. Colledge is a wild card, because he hasn't practiced all week. However, Colledge also is one of Miami's toughest players and said he's aiming to play. If Colledge cannot start, backup guard Dallas Thomas or Nate Garner will replace him. For the Chargers, running back Ryan Mathews (knee) has been ruled out, which is good news for Miami’s defense. Matthews gave the Dolphins trouble last season and rushed for 127 yards. San Diego linebacker Manti Te'o (foot) and cornerback Jason Verrett (shoulder) also were ruled out.
"Moving around, cutting, running, endurance," Cushing said. "Feel a lot better; just excited."
"Nothing's definite, but I feel good. I want to play and hope to play. That's the plan."
The Texans listed inside linebacker Jeff Tarpinian (knee) as out. Three players are questionable: Cushing, Jadeveon Clowney, who is dealing with a flu-like illness, and cornerback Darryl Morris, who could return for the Texans after being out with an ankle injury for several weeks. Morris did not practice on Friday.
What the Texans and Cushing are weighing are the pros and cons of bringing him back. He didn't feel like himself during the Texans' Monday night game, and the team decided it would be better for his knee to get some rest rather than play in Tennessee. If Cushing sits out this Sunday, he'd get three consecutive weekends off, as the Texans' bye week follows the Eagles game.
"Yeah, but I kind of don't think like that, you know," Cushing said. "Obviously I love playing, I want to be out there, but at the same time I want to play at my best level and feel as best as I can and have a good rest of the year. We gotta figure out a specific technique and formula that works for that to happen."
ASHBURN, Va. -- Robert Griffin III was ready to return a week ago. Jay Gruden was close to putting him back in the lineup. Then they decided to wait one more week.
Maybe it wasn't a direct nod to Griffin's injury past, but the Redskins didn't want to put him back in before he was fully ready.
"We wanted to give it more time and be smart about it," said Griffin, who will start Sunday at Minnesota for the first time since dislocating his left ankle in Week 2. "With the past, you learn from that and you learn from those mistakes. You learn from those trials and tribulations.
"I thank Coach for keeping me sane and allowing me to be involved with the game plans and everything. I had to keep my mind working when my body wouldn't."
Gruden said Griffin again received the majority of first-team practice reps this week, as he did in the lead-up to the game against the Cowboys, and that he will start Sunday barring a setback. Gruden added that there was no consideration given to resting Griffin another week, then having him face 1-6 Tampa Bay on Nov. 16 after a bye week.
"We [already] waited a week to get him ready," Gruden said. "He's had his time, he's had his rehab. There's no easy team on our schedule."
Like the other quarterbacks, Griffin is playing in a new offense in Gruden's first season. That's why Gruden wanted to make sure he was mentally ready to return, knowing that it was not only a new offense but that the offense had evolved since Griffin last played.
Griffin has stayed in the meeting rooms, so he is up to date on the changes.
"I think he's going to be fine," Gruden said. "Will he show some rust? Will he be perfect? No. But like I said before, Robert at 100 percent gives us the best chance to win Sunday."
While the 13 players who started on the injury report remain there, many of them took steps forward as the week has gone along. To the point that some players that many presumed might not be available this weekend will be probable for Sunday's game.
Of most pressing urgency, the offensive line and secondary look like they're going to have some of their normal options available. Starting right guard Rodger Saffold (shoulder) and center Scott Wells (elbow) participated fully in Friday's practice and are listed as probable for Sunday. Even backup center Tim Barnes (shoulder) has recovered enough to be considered probable.
In the secondary, the Rams will have more decisions to make with less certainty surrounding their options there. Cornerback Janoris Jenkins (knee) was the only Ram not to practice in some capacity Friday and he's listed as questionable against the Niners. He looks to be the most questionable of all the Rams after not practicing this week. Fellow cornerbacks Trumaine Johnson (knee), Lamarcus Joyner (hip) and Marcus Roberson (ankle) are listed as probable.
At safety, Rodney McLeod (knee) progressed enough to practice on a limited basis but will be one of the decisions that Rams coach Jeff Fisher has to make Sunday. Cody Davis has passed the concussion protocol and is also probable to play.
The other questionable Rams to monitor are defensive tackle Aaron Donald (shoulder) and linebacker Jo-Lonn Dunbar (toe). Both practiced on a limited basis Friday.
Here's the complete breakdown of Friday's injury report:
Questionable: CB Janoris Jenkins (knee), DT Aaron Donald (shoulder), S Rodney McLeod (knee), LB Jo-Lonn Dunbar (toe).
Probable: DE William Hayes (foot), G Rodger Saffold (shoulder), C Scott Wells (elbow), S Cody Davis (concussion), CB Trumaine Johnson (knee), C Tim Barnes (shoulder), WR Kenny Britt (hip), CB Marcus Roberson (ankle), DB Lamarcus Joyner (hip).
The Cincinnati Bengals' injury report.
The fourth-year receiver practiced all this week in limited participation as he tries returning from the injury to his right big toe that has been problematic all season. He has missed the past three games because of it.
It's possible he misses a fourth straight Sunday ahead of a short turnaround next week with a Thursday night tilt against the AFC North-rival Browns looming. That game has much more significance to Cincinnati's postseason hopes than Sunday's game against the 1-7, non-division Jaguars.
Mohamed Sanu, the receiver charged with replacing Green in the parts of four games Green missed, accounted for more than 31 percent of the Bengals' offensive production in those games. With all the time Green has missed, Sanu is Cincinnati's leading receiver. So there are reasons for the Bengals to believe they will be all right leaving the pass-catching part of their offense in Sanu's hands for one more week.
Aside from being questionable on the injury report, Green hasn't shown any ill effects of the injury in practice. He's still able to cut and run, albeit at slower speeds, much like he did before.
"If everything stays the way it is, he'll play," coach Marvin Lewis said Friday.
We'll keep our eye on Green when the Bengals first hit the field for warm-ups Sunday morning.
In addition to Green, the Bengals' injury report also has running back Giovani Bernard listed out with hip and clavicle injuries. Defensive tackle Brandon Thompson who practiced fully Wednesday and Thursday, is listed as questionable. He didn't practice on Friday, with Lewis saying Thompson was just being rested as the training staff continues to monitor his return.
Here is the Bengals' full injury report:
LB Vontaze Burfict (knee)
RB Giovani Bernard (hip/clavicle)
LB Rey Maualuga (hamstring)
CB Darqueze Dennard (hamstring)
OG Kevin Zeitler (calf)
DT Brandon Thompson (knee)
WR A.J. Green (toe)
DT Domata Peko (toe)
LB Jayson DiManche (shoulder)
DE Carlos Dunlap (illness)
OL Mike Pollak (knee)
CB Terence Newman (back)
OT Andre Smith (knee)
The Cleveland Browns tight end was ruled out for the game because of a concussion. Cameron was injured during the team's win against Oakland.
The situation at least raises the question of whether Cameron will be back for the road game against Cincinnati on Thursday night, four days after the Bucs game.
"That's always a concern when you have fewer days, sure," coach Mike Pettine said.
It's the third time in just more than two years that Cameron has missed time with a concussion, and the second time this season he's missed a game due to injury. He also did not play against New Orleans earlier this season, a game the Browns won with a last-minute field goal.
"There are certain things that Jordan can do that he's special at," offensive coordinator Kyle Shanahan said. "I think Jordan has a lot of talent, especially stretching the field, but I do feel very good about Barnidge and Dray stepping in. They're both good run blockers and they both can help us in the pass game.
"You don't feature them as much [as] you would a Pro Bowl tight end, but as far as going vs. zones and stuff and even some man-to-man situations, I think we'll be all right."
