Illinois sophomore guard Ayo Dosunmu suffered a gruesome-looking leg injury on the final possession of Tuesday's 70-69 loss to Michigan State.
Dosunmu, the team's leading scorer this season, was in the midst of collecting his dribble before a possible game-winning shot attempt when he slipped just to the right of the painted area.
He immediately grabbed his knee and had to be helped off the floor by members of the Illinois training staff.
"I don't know any more than you saw where he slipped and he'll go through the proper protocol with our doctors," Illini head coach Brad Underwood said in a postgame radio interview after the loss.
