Incredibly, the alleged incident happened in the very same ring as Tyson-Holyfield II 17 years ago, the MGM Grand in Las Vegas. Mike Tyson who bit Evander Holyfield's ear in their heavyweight contest then, was watching from ringside last night.

Mayweather, who nullified the threat of Maidana in smoother fashion than he did during their first fight in May, immediately complained to referee Kenny Bayliss in the eighth round. The fight was then briefly stopped before continuing. Maidana was not deducted any points for the incident.

He did lose a point in round 10 for rough tactices.

"He bit my left hand, so my fingers were numb," Mayweather said. "He's a tough competitor. I couldn't use my left hand. But I did what I had to do."

Maidana would later counter: "He was rubbing my eyes with his glove. Maybe he had his glove in my mouth. But I didn't bite him."
