Result: UD after Round 12

After an early scare that featured Judah nearly knocking Mayweather to the ground in the second round, Mayweather assumed control of the fight in the fifth and worked his way to a victory. But the real action came in the 10th round when Judah hit Mayweather with a low blow and a punch to the back of the head. It resulted in an all-out brawl in the ring with members of Mayweather's camp getting into it with Judah. Judah later had his boxing license revoked for a year as a result of the altercation.
