Two fans were competing against each other in the layup tic-tac-toe challenge (score a layup to place an X or O on the board) and while one fan got off to a hot start, the other seemingly messed up his knee real bad with a hard fall to the court.

During a game where fans have to make baskets to get pieces for a game of tic-tac-toe at center court, a fan appeared to suffer a devastating leg injury on his first layup attempt. As he was about to jump he appeared to slip and went down in pain, holding his knee.

As he went up for a layup, the Atlanta Hawks fan slipped and crashed to the ground holding his knee in obvious pain.
