Lucian Bute failed a doping test after his super middleweight title bout against Badou Jack, the World Boxing Council said it was notified by the D. C. Boxing and Wrestling Commission. 

The WBC said Thursday that the D.C. commission revealed it found the banned substance Ostarine. 

Ostarine, also known as MK-2866, is a drug that was developed in 2009 to treat conditions such as osteoporosis and muscle wasting. It causes muscle growth.

Bute and Jack fought to a majority draw in the April 30 bout in Washington. 

The 36-year-old Romanian-born Bute (32-3-1) is a former 168-pound champion. He's based in Montreal. 

"I don't understand what could have led to a positive test," Bute said in a statement in French. "I have always passed every test since I was world champion. Not long ago, before my fight with James DeGale in November, I was tested eight times from the start of training camp to the fight. I never took anything and I never used banned substances. I have complete confidence in my team. The B sample will be tested and I am sure the result will be negative."

Promoter Yvon Michel also said in the statement that he was surprised by the positive test.

"We hope that the test on the B sample shows it was a mistake," Michel said. "Until then, we solidly support Lucian Bute."
