Canadian curler Matt Dumontelle will serve a two-year ban after testing positive for Methandienone Metabolites, an anabolic steroid, following the gold-medal game at the World Men’s Curling Championship in Victoria earlier this year.

Dumontelle, of Sault Ste. Marie, Ont., served as an alternate under Brad Jacobs at the Canadian championships before his Northern Ontario rink finished second to Sweden at the worlds.

“I take full responsibility for the findings of the positive test at the World Championship in Victoria,” Dumontelle said. “I am truly sorry for letting down my teammates, the Canadian Curling Association and curling fans across Canada."

Dumontelle’s punishment won’t affect Canada’s silver-medal finish at the worlds. Dumontelle went on to claim he was unaware a workout supplement he had been using contained the banned agent.

“I had no intentions of trying to beat the system,” he said. “I was made aware by our Canadian Curling Association High Performance staff of my responsibilities to respect and follow the rules as set down by the World Anti-Doping Agency. At the end of the day I accept that it was, and is, my responsibility to make sure that I am playing by those rules.”

Dumontelle’s two-year sanction ends on May 6, 2015 (two years from the date of the provisional suspension being assessed), and makes him ineligible to participate in any sport that is part of the Canadian Anti-Doping Program during the time of the suspension.

“We have been informed of the positive finding for alternate player Matt Dumontelle, and while we remain friends with Matt, we in no way condone his actions,” said E.J. Harnden, Dumontelle’s teammate. “We respect the rules of the the World Anti-Doping Agency, and we also respect the process and the resulting penalty. Our team has undergone various in-competition tests this season with no adverse findings.”

Dumontelle did not participate in any games at the World Championship.
