As referee Lewis Garrison, who was positioned on the baseline behind the basket, whistled Michigan's Zavier Simpson for the foul, the official lunged forward into Cockburn's path.Cockburn, meanwhile, was busy celebrating his and-one. The 7-foot, 290-pound freshman whipped his right arm over his head and brought down his fist. His elbow collided with Garrison's head and, according to the Associated Press, knocked the referee unconscious.

Garrison immediately clutched his head in his hands and stumbled to the floor, and Cockburn lept forward to help the official. According to CBS Sports' Matt Norlander, Garrison was helped off the floor and into the back of the arena after spending minutes on all fours. Illinois spokesman Derrick Brunson said Garrison was cleared by doctors before he left the arena but still visited a nearby hospital for a precautionary X-ray.
