Celtics G Avery Bradley Loses to Youngster in Game of 'Knockout'

Not many people can say they defeated a professional athlete at their own game, but one youngster can boast about it for the rest of his life.

The best part: There's video proof.

Boston Celtics guard Avery Bradley took to the court to play a friendly game of "knockout" against some kids. While that seems like an unfair matchup, it was the pro hoopster who took the loss.

That's a defeat you can't even be mad about. Just give the kids props and hope for a rematch.
