Armenia's Khoren Gevor was disqualified in Saturday's boxing match against Robert Stieglitz of Germany for an intentional head butt in the 10th round.
After the result was announced, Gevor lost it and attacked several people from Stieglitz's corner and even went after the referee. He appeared to quickly get a few punches in before being restrained.
The Associated Press reported that Gevor had to be escorted from the ring.
Stieglitz retained his WBO super middleweight title. Scroll down to watch the video.
