Iowa has added Derrick Foster to its football staff, filling the spot that opened this month with the NCAA allowance of a 10th assistant coach. Foster previously coached running backs at Samford. He worked at Northwestern State in 2013 and at Tennessee in 2012. An Alabama native, Foster will coach on the offensive side at Iowa, allowing LeVar Woods to focus primarily on special teams, coach Kirk Ferentz said. Woods coordinated special teams last season for the Hawkeyes while also coaching tight ends.
