ROY JONES JR says he made a mistake agreeing to fight Mike Tyson.
The two heavyweight icons meet in a hotly anticipated bout on November 28 and Jones admitted he fears Tyson’s “explosive power”.
With a combined age of 105, many have criticised the exhibition contest.
And even Jones, 51, is having second thoughts.
He told Sky Sports: “He’s still Mike Tyson, he’s still one of the strongest, most explosive people who ever touched a boxing ring.
“If anything, I made a mistake going in with him. He’s the bigger guy, he’s the explosive guy.
“When it comes time to fight, we’re going to fight. If it comes down to bite, we’re going to bite.
“Whatever has to happen, is going to happen, that’s just what it is.”
Officially speaking, California State Commission rules state that both fighters will not look for the knockout in November, instead “exhibiting” their skills.
But there are fears the comeback fight could become a more feisty affair.
Jones added: “He’s going to have all the first-round fireworks, not me.
“I do have first-round fireworks, but he’s known for more first-round fireworks than anybody to ever touch boxing, other than maybe George Foreman.
“With him having the first-round fireworks, he’ll be against a guy smaller than him, maybe 40-to-50 pounds smaller than him.”
Danny Williams, who conquered an out-of-sorts Tyson, 54, back in 2004, fears the Brooklyn-born brawler will be keen to get physical and is worried about Jones.
He said: “I think Roy is going to get seriously hurt. He is a natural middleweight.”
Jones has showed he still has the skills required to succeed with his blistering pace on the pads in a video he posted to Instagram.
Working with coach Tom Yankello, Jones Jr was put through his paces at the World Class Boxing Gym in Pittsburgh.
Former world heavyweight champ Tyson has a natural size advantage over Jones – who traditionally competed in lower divisions.
