Starting from 7:50
Obvious back pass to the keeper, ref clearly signals for indirect free kick. Unfortunately as this happened the assistant injured himself and went down. After he was dealt with the ref does not give the free kick instead gives the ball back to the keeper.
He then apparently told his assessor that he "forgot" about the backpass.
I know we all make mistakes but someone of his level shouldn't be making mistakes as obvious as this.
Anyone seen worse than this?
