Promoter Frank Warren has rejected European cruiserweight champion David Haye's offer to fight Wales' WBO champion Enzo Maccarinelli.

Haye's team have offered Maccarinelli £150,000 for the fight, but Warren said the sum was not enough and added that Haye had demanded £250,000.
"Enzo is world champion and should be taking the lion's share," said Warren.
"Asking for £250,000 for Haye is outrageous. If Haye is so confident, he should step up and take a few risks."
Warren added: "Haye fights in front of a few hundred people at (London's) York Hall.
"Meanwhile, Maccarinelli is a genuine world champion, appears on prime time ITV and personally sold 3,000 tickets for one of his fights."
I'm not sure whether it is Warren or Maccarinelli shying away from the fight
A clash between Maccarinelli and Londoner Haye has been mooted for some time.
Maccarinelli, 26, has lost one of his 26 fights and claimed his world title this year when long-time champion Johnny Nelson retired.
After the first defence of his crown, a one-round defeat of Mark Hobson in October, he said he wanted to challenge WBC and WBA title-holder O'Neil Bell of Jamaica.
Haye, also 26, has lost one of his 18 encounters and made three defences of his European crown.
His clash with Italy's Giacobbe Fragomeni was billed as an eliminator for the WBC belt, but Haye's team say they now want Maccarinelli in April.
"We're looking at doing a no strings and no titles-attached 12-rounder for April," said Haye's manager and trainer Adam Booth.
"It is a fight everyone in Britain, and given the rankings and reputations both fighters are gaining, the world will want to see.
"I'm not sure whether it is Warren or Maccarinelli shying away from the fight. It must be one of them though."
However, Warren claimed Booth suggested he was not interested in the fight in previous discussions.
"Adam Booth has gone on record to say they are interested, but I've had conversations with him and he has told me they are looking to go in a different direction."
