Things went from bad to worse for the Blackhawks during their 4-3 overtime loss to the Winnipeg Jets.

Tommy Hawk was attacked by a fan on the United Center concourse on Friday, authorities say, in a video-recorded encounter that has made waves on social media.

Chicago police confirmed they were notified of a disturbance at the United Center around 11:15 p.m. Friday. Police said a “male was performing as a team mascot” when another man began punching him in the face and put him in a headlock.
