Mayweather Scores Controversial KO

Remains undefeated after a bizarre boxing match.

It's now being called "The Cheap Shot." In controversial fashion, Floyd Mayweather, Jr., knocked out Victor Ortiz in a welterweight title fight in Las Vegas Saturday night. Mayweather was dominating the bout when in the fourth round Ortiz intentionally head-butted Mayweather. Ortiz then embraced and kissed Mayweather in a gesture of apology, and the referee separated the two and docked Ortiz a point for the head butt. When the fight resumed, Ortiz again embraced Mayweather in the center of the ring when Mayweather cold-cocked him with a fierce left and a right that knocked Ortiz out, ending things early. It was ruled a legal punch. Watch the video here, and don't miss Mayweather's post-match tirade against 80-year-old HBO announcer Larry Merchant. "I wish I was 50 years younger and I'd kick your ass," Merchant told him.
