LONDON (AP) David Haye has pulled out of his all-British heavyweight rematch with Tony Bellew because of injury.
Haye said he tore a bicep muscle in a ''freak accident'' during a conditioning session.
Haye said the fight, which was scheduled for Dec. 17, will now take place on March 24 or May 5.
Bellew stepped up a weight in March to beat Haye, a world heavyweight champion from 2009-11, in a fight that ended in the 11th round. Haye fought the last five rounds with a ruptured Achilles tendon.
Haye said he has undergone a procedure and will be ''back in the gym to start my arm rehabilitation in two weeks.''
