Frank Warren has accused David Haye of ducking the Klitschko brothers.

WBA heavyweight title holder Haye is expected to announce on Tuesday that domestic rival Audley Harrison is the opponent for his second title defence.

It was hoped the 29-year-old from Bermondsey would fight either Vitali or Wladimir Klitschko but negotiations with his fellow world champions have stalled.

Instead, Haye has opted for Olympic gold medalist Harrison in a fight Warren claims is motivated only by financial reward.

"Haye's taken the easy option by fighting Harrison for the pay day and it's not what he said he was going to do," said the promoter

"Without a doubt he's avoiding the Klitschkos. He signed a contract to fight one of them and didn't carry it through, then pulled out against the other one.

"The reason he's not fighting one of them is because he wouldn't do a straight 50-50 split.

"Haye said he would fight them both. It's no good saying you'll do these things and then don't because you're looking to cash in.

"I look at Haye and I ask why does he only fight twice a year? He should be making money and not being inactive."

Warren, speaking ahead of his 'Magnificent Seven' bill in Birmingham on September 18, believes Haye's vulnerability gives Harrison a shot at victory.

"Monte Barrett wobbled Haye and then I fell asleep during the Nikolai Valuev fight," said Warren.

"If he gets hit on the chin then Haye will be knocked out and Harrison has that chance.

"Haye is streets above Harrison but he has a huge weakness - if gets hit on the whiskers he'll go."

Derek Chisora and Same Sexton meet for the British and Commonwealth heavyweight titles at the LG Arena and Warren believes either of them would welcome a clash with Haye.

"If Harrison can get a crack at the world title, it won't be a problem for me to deliver a shot to the winner of this fight," he said.

"Both of these fighters are better than Harrison. Look at where they are after 13 fights and look at what Harrison had done at the same stage.

"These two are decent heavyweights and can make their mark on the world scene. Even the loser could still pull through.

"Either of these guys would fight the Klitschkos, they won't duck anyone. They're fighters."
