Watch: Young son of boxing champ sucker-punches opponent in the groin before fight

Not cool dude. The young son of WBO middleweight champ Billy Joe Saunders might have thought he was being funny when he punched opponent Willie Monroe in the groin and then kicked him during the London weigh-in over the weekend. And Monroe seemed to be a good sport about it, but he's understandably not happy.

According to Huffington Post:

When Monroe tousled the boy's hair as he stood on the stage, Stevie Saunders pounded him in the groin and kicked him, the video above shows. And he appeared to do it with a smile...But Monroe wasn't having it. According to the BBC, he accused promoter Frank Warren of allowing the attack to happen. "Warren should be ashamed of himself," said Monroe, who demanded compensation for the incident and threatened to sue.
