Eddie Hearn has questioned whether Tyson Fury is a 'shot fighter' ahead of his huge clash against Oleksandr Usyk.
Fury and Usyk will enter the ring on February 17 and the promoter wonders if his best days are behind him.
Fury was below par in his last fight against Francis Ngannou in October.
Ngannou, participating in his first professional boxing bout, knocked the Gypsy King down and only lost via a split decision.

Anthony Joshua will face Ngannou in March following his impressive display against Fury.
Joshua rejected the chance to fight the 37-year-old before he saw how he performed on his boxing debut.
Hearn has raised the possibility that Ngannou's showing three months ago was a 'one-off'.
But he also thinks there is a chance that Fury has dropped his level considerably and is now 'shot'.
Hearn told the Mirror: "We had the opportunity to fight Ngannou before but AJ didn't want to do it.
"He said he is a serious guy who wants to win a heavyweight championship.
"But I thought Ngannou beat Fury, if he didnt, it was a draw, or he lost by a round, it was that close.
"He dropped Fury and that gave him credibility. What we don't know is was it a one-off?
"But we know the confidence he has from that fight will push him on in this fight, but we've seen him now and Ben Davison has 10 rounds to come up with a gameplan.
"Maybe [Fury] is a shot fighter, we'll find out on February 17."
"It's very difficult to imagine going into a fight having no idea what the other guy is going to do.
"You've got to figure it out from the first bell.
"How big a puncher is Ngannou? People tell us he's a monstrous puncher but is Fury's chin going? We'll have to find out."
Fury and Usyk will put all their belts on the line in Riyadh.
They will finally put years of trash talk behind them.

But Fury's dad John says his son must change his approach from previous fights or he could be made to look a 'fool'.
He told the Daily Mail: "That style he had for those three fights against [Deontay] Wilder will not beat Usyk. They're two different people.
"Usyk is a class boxer. He's tricky, his coordination is good, his movement is good, he leans out of the way of punches and he's hard to pin down.
"If you can't set traps and pose problems for a man like Oleksandr Usyk, he's just going to make a fool out of you in the ring.
"At the end of the day, that straight-up Kronk style, what he [Tyson] was doing with Francis Ngannou won't work against Usyk.

"Ngannou wouldn't have been able to land a glove on the old Tyson.
"That style they've got only worked against Wilder because Wilder is a one-trick pony.
"Wilder couldn't box going back, Wilder couldn't box full stop. Wilder was there to be hit. All Wilder had in his arsenal was a big punch and bravery.
"He was a brave man with a big punch. But, that style [Tyson's style], you wouldn't need to be a brain surgeon to work it out.
"It's no good living off your morals on those wins."
