Scuffle erupts in ring after Judah's low blow to Mayweather

LAS VEGAS -- A melee broke out between trainers and support staff for welterweights Zab Judah and Floyd Mayweather Jr. on Saturday night after Judah hit the challenger with two illegal blows.

With Mayweather seemingly in a comfortable lead late in the 10th round of the fight for Judah's IBF welterweight title, Judah sent Mayweather to the canvas with a left hook to Mayweather's groin and a right to the back of his head.

Mayweather's trainer and uncle, Roger Mayweather, jumped into the ring in an attempt to challenge Judah. Members of both fighters' corners followed into the ring, and several police officers and security personnel stormed the ring to restore order.

After perhaps five minutes of confusion, the bout resumed.
