A collision between two motorcross riders descended into a punch up at Satruday's AMA Supercross event.

Weston Peick was not too impressed with competitorm, Vince Friese when he cut him off in a move that resulted in the two colliding and falling off the track. 

Peick wasn't shy about expressing his feelings to Friese as you can see in the video below. 

As you can see from the video, Peick had a pretty good reason to be annoyed with Friese considering he knocked him off the track not once but twice but his reaction may have been over the top. At least that's what the AMA thought when they handed him a one race suspension and a $5,000 fine. 

Fighting on a motorcross track is unusual but not unprecedented. The most notable case being this brawl between Tyler Evans and Keith Johnson in Vancouver in 2006.
