It's probably safe to say that boxers Billy Joe Saunders and Willie Monroe Jr. don't like each other. Their rivalry also extends to family members too. The two square off tomorrow night for the WBO middleweight title and at the weigh-in, Saunders' son got involved. He came up on stage and stepped on the scale while the two boxers were posing and Monroe patted him on the head. Little Saunders responded with a solid right below the belt. The punch is at 3:40 if the video doesn't start at the right time.
