Illinois senior defensive back Terry Hawthorne is undergoing further tests to determine whether he suffered a concussion last weekend against Wisconsin.

Hawthorne left the field on Saturday in an ambulance, but initial scans were negative. He was able to travel back to Champaign with the team, and is currently being examined.

According to coach Tim Beckman, Hawthorne would not have participated if the team had held practices on Monday. His status for Saturday's game against Michigan remains uncertain.

Hawthorne and the rest of the Illinois secondary will prepare for the unique Michigan offense. The Wolverines average only 188.4 passing yards per game, but depend on quarterback Denard Robinson for over 135 rushing yards per game. Still, Robinson is prone to interceptions; he has thrown eight in five games this season.

Hawthorne is a native of East St. Louis, Ill., and was the Defensive MVP of the 2011 Kraft Fight Hunger Bowl.
