Middleweight world titleholder Billy Joe Saunders has failed a Voluntary Anti-Doping Association drug test for the banned substance oxilofrine, a stimulant, multiple sources with knowledge of the test results told ESPN on Thursday. Saunders is preparing for an Oct. 20 defense against Demetrius Andrade in Boston but the fight could be canceled and Saunders could be stripped of his 160-pound world title.
