A leukaemia charity is to benefit by £20,000 from boxer David Haye's victorious weekend bout.

Former WBA Heavyweight Champion David 'Hayemaker' Haye knocked out Dereck Chisora, at their much-anticipated grudge clash at Upton Park on Saturday night.

Defeated Chisora, who was knocked out in the fifth round, said he would honour the pre-match bet he made with Haye and will be making a £20,000 donation to the African Caribbean Leukaemia Trust (ACLT).

The charity, which Haye is a patron of, has said it is "delighted" by the donation, which will be used to support the charity in their work to spread awareness and increase the number of bone marrow, blood and organ donors from ethnic minorities.

Speaking after the match, Chisora said: "I am a man of my word, I'm happy the £20,000 donation will make a difference to the life saving work the ACLT carries out."

The ACLT was formed in 1996, when co-founders Beverley De-Gale and Orin Lewis from Croydon received the news their son Daniel would need a life saving bone marrow transplant in order to win his three year battle against leukaemia.

Daniel overcame leukaemia, but died aged 21 in 2008 from an unrelated illness.

Since then, the pair have dedicated their lives to encouraging people from the black community to donate blood and bone marrow to help others.

Mr Haye said: "I have been a patron for the ACLT for many years now, I'm happy Dereck and I are able to make a difference to the wonderful work the charities co-founders work so tirelessly for."

A spokeswoman for the ACLT said: "We are delighted to report we have spoken directly to both our patron David Haye and Dereck Chisora.

"A cheque of £20,000 will be donated to the ACLT by Dereck Chisora, as a result of the pre-match bet made between him and David Haye.

"We are sincerely grateful to them both and look forward to receiving the generous donation later this week."
