Coleman injured his ankle midway through the fourth quarter and had to be helped off the field.
Kevin Wilson said Monday at his weekly press conference that Coleman "has a good ankle sprain" and in all likelihood would miss the Wisconsin game.
It wasn't completely definitive but generally when Wilson rules someone out on Monday they don't play the following week. Wilson said it's a good thing that IU has depth at that position with Stephen Houston and D'Angelo Roberts.
Coleman has 958 yards rushing this season and leads the Big Ten with 12 rushing touchdowns.
