Canadian promoter Yvon Michel said Thursday that four fighters he represents — all based in Montreal and all among the best fighters in their respective divisions — have enrolled in the WBC’s Clean Boxing Program.

Light heavyweight world champion Adonis Stevenson, as well as light heavyweight contenders Eleider Alvarez and Artur Beterbiev and former super middleweight world titleholder Lucian Bute, will participate in the program, which is run by the Voluntary Anti-Doping Association on behalf of the WBC. Their enrollment means they can be randomly drug tested — blood and/or urine — at any time 365 days a year. They must be available at all times for any testing.

“I am fully in favor of these new measures so all of us in the program will be playing on the same playing field,” Stevenson said.

The WBC is in the process of implementing the program. All of the fighters ranked in the sanctioning organization’s top 15 in all 17 weight divisions have until Sept. 9 to conform to the new protocol or they will be removed from the WBC rankings and suspended from any activity in the WBC.

“Fortunately, boxing is rarely the target of doping cases, but tightening the rules can only be beneficial to prevent tempted athletes to follow the wrong path,” said Bernard Barre, vice president of operations and recruitment for Michel’s GYM promotional company.

Bute’s enrollment comes at a time when he is dealing with the fallout from a failed drug test after his last fight, a majority draw against super middleweight titleholder Badou Jack on April 30 at the DC Armory in Washington, D.C.

Bute’s A sample tested positive for the banned substance ostarine (also called enobosarm), which is supposed to increase stamina and recovery ability. Results are pending for his B sample.

“The WBC is proud to see the exemplary dedication of GYM for the welfare of the sport, and we are grateful for their support to enroll champion Adonis Stevenson and all of their WBC top 15-ranked fighters in the WBC-VADA Clean Boxing Program,” WBC president Mauricio Sulaiman said. “The CBP is the first-ever attempt in our sport to have a safety platform for our athletes and, more importantly, to share the much-needed information on PEDs and illegal procedures, which could harm our heroes of the ring.”
