Eddie Hearn thinks Dillian Whyte should focus on either Deontay Wilder or Andy Ruiz Jr next, rather than face Alexander Povetkin in a trilogy bout.
On Saturday night, Whyte avenged his defeat to Povetkin with a brutal fourth-round stoppage.
The victory saw Whyte regain his WBC interim strap and ultimately remain in line for a world title shot.
Whyte reportedly offered his opponent a trilogy bout after the win, but promoter Hearn has now cast doubt on that fight.
"He can't win a world championship now, and I think that's the only thing Povetkin is in the game for. He's got a lot of money and he's got great memories of some historical fight nights.
"But I don't think he wants to be in there trying to work his way back to a world championship. That'll probably be it for him now.
"He's a very tough man and an honourable man. He gave us a scare at Fight Camp, but luckily we got the win on Saturday and ended that process."
Hearn, who heads Matchroom Boxing, will now likely focus on a highly-anticipated bout between Whyte and Wilder.
Wilder hasn't fought since Tyson Fury took his WBC belt with a great performance in February 2020.
Speaking about Whyte-Wilder, Hearn continued: "Wilder is a huge name in America now after those two fights with Fury.
"He's also a big name in the UK. We can work out a deal. We need to see Wilder back in the ring. I want to see that - I think he's great for the sport.
"Dillian has had such a long run of tough fights. I would like to see him come to the States in the summer and fight."
Hearn also suggested that Whyte could face former world champion Ruiz Jr or American contender Trevor Bryan, who is ranked number two by the WBA.
If he overcomes one of those three fighters, then a world title shot could be next for Whyte.
