Dereck Chisora has said that he will give £20,000 to Great Ormond Street Hospital if David Haye knocks him out on Saturday.
The pair will step into the ring at Upton Park tomorrow night to settle their dispute, which famously erupted during a post-fight press conference in Munich in February.
Chisora, a former British and Commonwealth heavyweight champion, confidently declared: "If Haye knocks me out, I will give £20,000 to the Great Ormond Street Hospital for Children.
"If I knock Haye out, then he has to give the same amount to the charity of his choice."
Chisora weighed in over two and a half stones heavier than Haye at today's weigh in.
