FANS are fearing for Evander Holyfield if he steps back into the ring with Mike Tyson after leaked footage appeared to show the 57-year-old looking painfully slow.
There has been plenty of talk about a trilogy fight between the American pair after they both announced plans to return to action for charity bouts.
Tyson, 53, is back in the gym working while Holyfield is also plotting a sensational comeback, nine years after his last bout.
No fight has yet been agreed between the pair, who met twice in the 1990s, but Holyfield is not wasting time in whipping himself into shape.
But despite a promo video suggesting he was in pretty decent shape, a behind-the-scenes clip doing the rounds online suggests otherwise.
Holyfield stepped up to a loaded sled but didn't even move it before walking off and in the ring he looks to have lost most of his speed.
Training on the pads, he could only manage a couple of lethargic combos.
The four-time heavyweight champ has an experienced team with him.
Holyfield has brought heavyweight legend Wladimir Klitschko into his camp to help with the training.
But it appears the Ukrainian has his work cut out.
The slow speed from Holyfield makes grim viewing for his supporters - especially after Tyson looked electrifying in a training video of his own.
And boxing fans agreed.
One said: "He looks slow and stiff, especially compared to the recent clips of Tyson. Holyfield is going to get worked over if they do fight."
Another wrote: "Holyfield’s always in shape but he’s too punch drunk to compete again. Bad idea."
A third added: "Mike is moving like he’s in his last 20s. He’s going to beat Evander up!"
Tyson, meanwhile, is keen to get an exhibition fight arranged.

“I’m in good shape, I feel really good. Anything is possible. I’m having fun, looking good, showing off my new body and stuff.
“Hey listen, there are a lot of people out there that need help and something like that could help a lot of people that’s in need for help.”
