I think we must have different definitions of "pushes". Harris is 4 feet away from him and after he releases the ball Harris puts his hand near his hip to block out. I don't see a "push" anywhere. I am not convinced he even touches him. Certainly nothing to call a foul on.. and definitely nothing to hip check Sacre over and get tossed from the game. Funny thing is, Sacre wasn't even the guy guarding him. Sacre would have at least put his hands up. Harris is too lazy for that.
