Mayweather McGregor Press Conference London

Floyd Mayweather and Conor McGregor are making bold predictions about their upcoming fight.

After Conor said he thinks he can KO Floyd in 10 seconds, the boxer is offering a promise of his own. No decision… a knockout.

While speaking to ESPN on Wednesday (Aug. 23), Mayweather said he is guaranteeing a knockout victory. “One hundred percent, it will not go the distance,” he said. “One hundred percent chance this fight won’t go the distance.”

Throughout his career, Mayweather has made a living off being one of the most skilled defensive fighters ever. In 49 fights, he’s only scored 29 knockouts, the last being against Victor Ortiz in 2011. His wins usually come by decision.

When asked what he says to critics who don’t believe he can score a KO, Mayweather replied: “I’ve never known a critic to get in there and be a fighter. All a critic do is criticize you, because they can’t do what you can do. So, I don’t listen to critics.”

Mayweather-McGregor takes place at the T-Mobile Arena in Las Vegas on Saturday (Aug. 26).
