Mike Tyson vs. Roy Jones Jr. I'm Worried They'll Get Seriously Hurt ... Says George Foreman

George Foreman says Mike Tyson and Roy Jones Jr.'s return to the boxing ring is a "beautiful thing" ... but admits he is scared the legendary pugilists could be seriously hurt.

TMZ Sports broke the story ... 54-year-old Tyson and 51-year-old Jones Jr. are coming out of retirement to put on a massively anticipated 8-round exhibition fight -- and combat sports fans are PUMPED!
But, Foreman -- who had 81 professional bouts against immortal fighters like Muhammad Ali and Joe Frazier -- says he's very concerned about "Iron Mike" and RJJ's well-being.

"There's a time when you gotta worry about your health, but it's a beautiful thing that they would even come out," George says.
"Maybe they can even name a charity or something for the recipient of the funds. I think it's good to come out but its gotta be a fun thing, but I hope one does not hit the other."
