During the third period of Saturday's game between Pittsburgh and Tampa Bay, Lightning defenceman Haydn Fleury collided with Steve Kozari at center ice and it appeared that the referee was knocked out cold. Medical staff came immediately rushing to the scene to help Kozari.
Eventually, after being down on the ice for several minutes, Kozari was moved to a stretcher and left the game. Both Pittsburgh and Tampa Bay's benches cleared as Kozari was being stretchered off as a sign of support and respect.
