Mike Tyson says he could've fought in UFC, but has 1 weakness

Mike Tyson believes he could've been just as successful in mixed martial arts as he was in boxing, so long as none of his opponents stepped on his feet.

The 54-year-old former world heavyweight champion revealed his weakness in an interview with TMZ Sports.

"I could've done all that stuff," Tyson said when asked if he thinks he could've been a UFC champion. "I could've done all that stuff, but once someone stepped on my foot, I would've tapped out. My feet are my weak spot. You step on my feet, I'm gonna tap out."

Unlike in boxing, stepping on an opponent's feet isn't illegal in MMA.

Tyson is set to make his return to the boxing ring Nov. 28 in an exhibition match against Roy Jones Jr.
