Haye stopped Harrison in the third round in Manchester
Promoter Frank Warren has questioned the ethics of David Haye betting on himself to beat Audley Harrison.
WBA heavyweight champion Haye claimed after his third-round stoppage of Harrison in Manchester that he had bet on himself to win in that round.
"For a fighter promoting it who is in the ring I think it is unacceptable," Warren told BBC 5 Live's Sportsweek.
And BBC boxing commentator Mike Costello said Haye could face action from the British Board of Control.
The board forbids a fighter from betting on himself and Costello added that Haye will have some explaining to do.

"If Haye is found to be in breach of the rules he could be fined or possibly let off with just a warning," Costello stated.
"In reality there is little the board can do to police such matters but they have to be seen to be discouraging the practice."
Costello added: "There have also been calls for Harrison's purse to be withheld after his woeful performance but the feeling is the public humiliation he suffered on Saturday night will stay with him for a long time and is punishment enough."
And Warren, who believes any such bets undermine the sport, added: "It shouldn't be allowed to happen. It is not as though they're not getting a fortune to fight in the first place.
"If I was a member of the public and that happened, I don't think I would be too happy about it.
"I'm sure the board of control will make its own decision on that but I don't think it looks good for the game or David Haye if it is true that he had that bet."
However, fellow promoter Frank Maloney said there is nothing to stop fighters such as Haye from betting on a round for victory.
"[If] he can earn some more money and he believes in his ability that's up to him," suggested Maloney. "Sportsmen bet on themselves. I don't think there's anything to stop them [boxers betting on themselves]."
And former WBC super-middleweight champion Carl Froch also said that there is nothing wrong with a fighter backing himself in such a fashion.
"I've got nothing against it, if a fighter is that good - if he can hold someone up for a couple of rounds and then finish him when he says he can," Froch argued.
"It's not match-fixing because that would be saying you've put a load of money on the fight and then taken a dive in a round.
"He didn't publicise it before the fight so it might have just been a publicity stunt."
A spokesman for leading online betting exchange Betfair told BBC Sport a Haye third-round victory was priced at about 8-1, although no suspicious trading patterns were reported.
And Graham Sharpe, a spokesman for bookmakers William Hill, defended the boxer nicknamed 'Hayemaker'.
"Muhammad Ali used to regularly claim he deliberately waited for latter rounds to win fights to maximise TV advertising revenue between rounds," said Sharpe.
"I didn't believe him, and I don't believe any boxer can win enough by backing himself to win in a certain round to run the risk that by waiting until that round he might lose the fight in the meantime.
"Haye seemed to me to be speaking in a light-hearted manner after the fight."
However, Froch did admit that he would have expected Haye to have ended the fight earlier if an opportunity had presented itself.
"You can't predict what round you're going to beat somebody. It can be your undoing," Froch reflected.
"You say you're going to knock someone down in round three and go for a swing you can end up walking into a shot or rush something. All good boxers will tell you, when you look for the knockout it doesn't come.
"If David Haye had sensed a chance and Audley had thrown a left-cross last night and fell short, trust me David Haye would have jumped on him and hit him with a big counter-punch and followed with a big combination."
