With 4:09 left in the second quarter, Kemba Walker hit a step back three over Ish Smith of the Detroit Pistons. On the play, Andre Drummond and Roy Hibbert were battling for rebounding postion in which Andre Drummond threw an elbow at the back of Hibbert’s head.
The officials then went to the monitor to look at the play. Upon further review, they assessed Drummond a flagrant-2 foul resulting in a mandatory ejection. Looking at the play again, it looks like Drummond’s elbow makes some contact with Hibbert’s head but for the referees to give him a flagrant-2 for that action is questionable.
