Eddie Hearn reckons Tyson Fury could be "packing up boxing" in order to focus on interests outside the ring.
Unbeaten heavyweight Fury is set to step into the WWE ring for his wrestling debut against Braun Strowman at WWE Crown Jewel on October 31.
His Saudi Arabia showdown is set to net the Gypsy King a reported £12m fee - just months after signing a big-money £80m deal with Top Rank and ESPN.
After headlining in Las Vegas in wins over Tom Schwarz and Otto Wallin, Fury is expected to take on Deontay Wilder in a long-awaited rematch in 2020.
But he has instead spent recent weeks focusing on his WWE cameo, the release of a new autobiography and an attempt to land the Christmas No.1 in a duet with Robbie Williams.
Matchroom Promoter Hearn has praised Fury for building his profile - but suggested he has lost his hunger for boxing and could quit the sport.
Speaking to iFL TV, he said: "Listen Tyson’s [Fury] on a roll right now, he’s going for it. He’s got a Christmas single coming out, he’s doing WWE wrestling - his heads gone completely but he’s absolutely living life, so good luck to him.
“I think he’s packing up boxing, I really think that he’s looking at it and thinking 'I’ve made a nice few quid over the last few fights, I’m enjoying life.'
“I just think he’s looking at this other world and going 'do you know what, this is a lot more fun than getting my head punched and going into camp.'
“I’m sure he’ll fight again but I don’t think he’s got the hunger.
“It’s hard, look, all of a sudden he’s earned some great money, he’s prancing around in Los Angeles getting in the ring doing all this cringey stuff with the WWE guys everyone’s loving it - it’s brilliant for him.
“He’s got the Robbie Williams thing, good luck to him.
“I don’t believe he has the same hunger, that he had, well certainly pre-Klitschko, but even pre-Wilder.
"As long as he’s happy and healthy good luck to him, I think he’s hilarious."
