Michael Jai White, star of 2009 film 'Black Dynamite', has urged boxing's pound-for-pound king Floyd Mayweather to stay away from the MMA ring.

The 46-year-old, who does a lot of MMA training and has a black belt in several martial arts, believes he would comfortably defeat Mayweather if they went head-to-head in his sport.

When asked by TMZ whether he believed Mayweather could take him in an MMA bout, White responded: "No he wouldn't wanna do that.

"Floyd's half my size, that's not fair. There's a size different and skill difference thing - it's cheating."

White added: "I'm 235, he's like 145. I'm twice the dude's size."

This isn't the first time that someone from another sport had spoken out about their ability to beat the WBC welterweight champion, who has never lost a professional fight.

Earlier this year, the reigning UFC women’s bantamweight champion Ronda Rousey revealed how she would beat Mayweather if she found himself in the ring with the 37-year-old champ.

But would Floyd 'Money' Mayweather stand a chance against any MMA or UFC fighters? After all, that punch of his could take down almost any fighter in the world.
