BERLIN (AP) -Spanish boxer Pablo Navascues has lost his chance of fighting Sebastian Sylvester for the IBF middleweight title after failing a doping test during training.
Promoter Sauerland Event said on its Web site Saturday that Navascues tested positive for banned substances during a random test earlier this month. Sauerland did not disclose what Navascues tested positive for.
Sauerland general manager Chris Meyer said the company has a ``a zero-tolerance policy'' and was glad the testing ``paid dividends.''
Germany's Sylvester will now make his first title defense against American Billy Lyell instead.
The fight is scheduled for Jan. 30 in Neubrandenburg, Germany.
