Billy Joe Saunders has failed a voluntary drugs test ahead of his WBO middleweight title defence against Demetrius Andrade, according to reports.
The English boxer, who last week received a £100k fine over a controversial video in which he was seen offering a woman drugs, tested positive for the banned stimulant oxilofrine, according to ESPN.
Saunders became the WBO middleweight world champion when he beat Andy Lee in December 2015. He previously held the European, British, and Commonwealth middleweight titles.
Unbeaten in 26 fights, he is due to defend his title against American Andrade in Boston on 20 October, but is likely instead to be stripped of his world title.
