SHANNON BRIGGS may be 48 years old, but the former world heavyweight boxing champion is still looking like a formidable fighter.
Briggs showed off his ripped physique during a training camp after signing up for bare-knuckle boxing.
And he penned a deal with BKFC in April, even though his last professional bout came in 2016.
The fighter appears to be in tip-top shape as he hunts his first opponent in the heavyweight field.
Despite his new adventure in bare knuckle, Briggs recently claimed he has agreed to fight legendary boxer Mike Tyson.
Iron Mike has come out of retirement at the age of 53.
And he looks to be in great shape too after being linked with names including Evander Holyfield and Floyd Mayweather.
With a combined age of 101, a showdown between Tyson and Briggs would certainly be an intriguing one.
Briggs said: “I just talked to Mike Tyson, it’s going down, me and Mike.
“We’re going to make it happen, it’s official, you’re going to see it happen, Brownsville versus Brownsville.
“Me and Tyson are going to lace up the gloves, we’re going to rumble, rumble in the jungle.
“We’re going to let our fists do the talking.
“The money is there, the money is almost three. I can’t say much, I’ll leave it at that.
“This is for charity, this is exhibition, I want people to understand.
“We all know it’s an exhibition and then we will see what’s left in the tank.
“It’s for charity, it will be fun, but this is Mike Tyson we are talking about.
“He naturally hits hard, so he might hit me and he might break my rib. We have to be fully prepared.”
