Mike Tyson says if he would’ve gone into mixed martial arts — instead of boxing as a teenager — he would’ve been a helluva MMA fighter … as long as no one stepped on his feet!!

Yes, one of the most ferocious men the world has ever seen has a weakness … and it’s having his feet stomped.

360APROKO Sports talked to 54-year-old “Iron Mike” — a huge UFC fan — about how he would’ve fared if he dedicated his life to a different combat sport.

“I could of done all that stuff,” Tyson says.

“I could of done all that stuff but once someone stepped on my foot, I would of tapped out. My feet are my weak spot! You step on my feet, I’m gonna tap out!”

FYI, if you’re not familiar with MMA rules … stomping on your opponent’s feet IS allowed.

Tyson — who has recently worked with fighters like Francis Ngannou and Rashad Evans — started boxing at an early age … and became the youngest heavyweight champion of all-time at 20 years, 4 months when he beat Trevor Berbick in 1986.

UFC 1 didn’t take place until late-1993 … while Tyson was in prison.

Still, ya gotta wonder how Tyson — with his insane natural ability and work ethic — would’ve fared if he chose the Octagon over the squared-circle.
