Team Sky cyclist Gianni Moscon punched fellow cyclist Elie Gesbert of Team Fortuneo during Stage 15 from Millau to Carcassonne of the Tour de France.  

Moscon was later kicked out of the competition for the punch.  He released a statement after receiving the boot.

Via NBC Sports:

“I’m sorry for today’s incident, and I totally regret my actions,” Moscon said. “I would like to personally apologize to Elie Gesbert…. What happened was wrong and was a bad example coming from me to everyone, and I want to publicly apologize. … I make no excuse for it and accept the decision of the race organizers.”

Here’s footage of the punch.  Which you have to admit is pretty impressive to pull off while riding a bike.  Turning around while riding a bike is hard enough, no wonder they’re considered world class athletes.
