Michigan put Denard Robinson back in the starting lineup — at running back.
The senior lined up behind quarterback Devin Gardner in his final home game and gained 3 yards on a toss sweep the first time the 23rd-ranked Wolverines were on offense Saturday against Iowa.
Gardner made his third straight start at quarterback in place of Robinson, who had been out with nerve damage in his right elbow.
Robinson caught a pass on Michigan's second play for a gain of 4 yards. He finished with 98 yards rushing on 13 carries, including a 40-yard run. He added one more reception, during which he reversed field from sideline to sideline and gained 20 yards.
Robinson later took a shotgun snap and handed the ball off as a quarterback. Then, he got a handoff from Gardner and made an option pitch to Fitzgerald Toussaint for a first down. Toussaint was injured on the play and was carted off the field with a brace on his left leg, which appeared to be broken between his ankle and knee as he was tackled by two Hawkeyes.
Michigan coach Brady Hoke said Toussaint was sent to a hospital for surgery soon after he was hurt.
