One UFC fighter, Jon Koppenhaver has been arrested recently.

A former top MMA fighter known as the War Machine is in big legal trouble this week, after being arrested for assault. The UFC fighter who was once a top contender has had legal problems before, but faces his biggest tangle yet as he faces charges of assault with a deadly weapon.

Technically Jon Koppenhaver only fought two fights for the UFC and most of his fights were in other leagues, so some say the UFC is abusing his name for publicity by talking to news outlets like TMZ (did i just call TMZ a news outlet?) about War Machine as a UFC name.
