HELSINKI (AP) - Ruslan Chagaev failed a "medical requirement" on Friday, forcing his challenge for Nikolai Valuev's WBA heavyweight title to be called off a day before the fight.
Finnish officials said "Chagaev has been unable to fulfill the Finnish Boxing Federation's medical requirements" but gave no further details.
Federation president Pertti Augustin and press spokesman Pekka Kaidesoja refused to offer explanations, saying "it's against Finnish law to do so."
Chagaev would have earned 55 percent of the $2.8 million purse.
It's the third time their rematch has been called off since Chagaev gave Valuev his only pro defeat in April 2007. The previous two rematches were canceled after Chagaev ruptured his Achilles' tendon in training.
