Tour de France fight? This is not hockey, guys!

The Tour de France just became a contact sport. Spain's cyclist Carlos Barredo and Portuguese competitor Rui Alberto Costa got into a bit of a slap down -- with a bike wheel as a weapon -- at the end of Friday's (July 9) sixth stage.

Barredo and Costa got into it after the finish line, apparently over an incident earlier in the race.

Barredo ran toward Costa wielding his front wheel(!) and attacked Barredo with it. After a few punches were exchanged, the scuffle was stopped and the guys were separated by officials.
