A fracas broke out in the stands at Sports Authority Field amid the Broncos' loss to the Patriots on Sunday night.

Caught on video was a Broncos fan getting sucker-punched by another fan during the game, evidently for not allowing the handicapped assailant to move through the aisle.

It's unclear what happened to the man who threw the punch, but there's no place for this type of behavior at sporting events -- or anywhere else.
