IBF heavyweight champion Wladimir Klitschko is against Floyd Mayweather Jr's possible entrance into the world of mixed-martial-arts. As quoted in a recent ESPN interview by writer Michael David Smith, Klitschko is afraid that Mayweather will get seriously hurt if he decides to follow through with his plans for a mixed-martial-arts debut. 

"Please, Floyd, don't do it," Klitschko said. "I think he'd get hurt. There are so many difficulties from changing one sport you've been doing for a long time and swithcing to something else. ... I wish he'd stick with boxing."

Klitschko's comment has been echoed by several high-profile personalities in the business. A few weeks ago, Mayweather met with Dallas Mavericks owner Mark Cuban, who also owns HDNet Fights, to discuss a possible deal for a future MMA bout.

Most in the sport view the meeting with Cuban as nothing more than a publicity stunt. If the unthinkable happens and Mayweather actually decides to venture into MMA, it's very unlikely that his opponent will be a legitimate threat.
