The Saints will be thin at guard against the NFL's No. 1-ranked defense on Sunday in Baltimore. Starting LG Andrus Peat has been ruled out with a concussion. Pro Bowl RG Larry Warford is questionable with a back injury. And backup G/T Jermon Bushrod is questionable after missing two days of practice for non-injury reasons. Warford practiced on a limited basis Friday after missing Thursday's practice. The Saints have an experienced backup at left guard in veteran Josh LeRibeus, who started two games in place of Peat earlier this year. However, they may have to go with inexperienced second-year pro Cameron Tom or recently re-signed veteran Michael Ola if Warford and Bushrod aren't available. ... Saints DT Taylor Stallworth (ankle) has also been ruled out.
