The University of Iowa has not released an injury report on Robinson. When asked about directly if the RB had a concussion on his radio show Wednesday night, Hawkeye Coach Kirk Ferentz said he had a lot of players hurt and avoided speaking specifically about his sophomore back.
Robinson left last week's game against Michigan State early in the third quarter. He looked woozy. Sources told Hawkeyeinsider.com earlier this week that the Des Moines native was sent home from practice on Tuesday after being diagnosed with a concussion.
Robinson has rushed 172 times for 806 yards and 10 touchdowns this season. He's exceeded 100 yards on the ground in five of Iowa's first eight games.
True freshman Marcus Coker or red-shirt freshman Brad Rogers could step into the starting lineup for Robinson. Senior Pakie O'Meara might be a candidate, but has been limited on special teams after suffering multiple concussions.
Coker carried the ball a career-high 16 times for 40 yards against Michigan State. It represented his first action since seeing his first college playing time against Ball State on Sept. 25. He rushed 10 times for 60 yards in that contest.
Rogers toted the ball nine times for 66 yards against Ball State. He hasn't received a carry since that game.
