Adam Hunter’s planned UFC debut was canceled due to a potential anti-doping violation. Now, it’ll have to wait at least a few more years.

The U.S. Anti-Doping Agency (USADA) and British Columbia Athletic Commission (BCAC) today announced the Canadian fighter has received a two-year sanction after testing positive for multiple prohibited substances.

Just a day before his bout against middleweight Ryan Janes (8-1 MMA, 0-0 UFC) in August at UFC on FOX 21, Hunter (7-1 MMA, 0-0 UFC) was informed of a potential USADA anti-doping violation stemming from a pre-fight out-of-competition drug test. Today, in a press release, officials stated Hunter tested positive for amoxifen metabolite, boldenone metabolites, methandienone metabolites, drostanolone metabolite and clenbuterol.

According to USADA:

‘These non-specified substances are prohibited at all times under the BCAC Anti-Doping Policy and the UFC Anti-Doping Policy, both of which have adopted the World Anti-Doping Agency (WADA) Prohibited List. On the WADA Prohibited List, tamoxifen is a substance in the class of Hormone and Metabolic Modulators, while boldenone, methandienone, drostanolone, and clenbuterol are substances in the class of Anabolic Agents.

“Under the UFC Anti-Doping Policy, the standard sanction for an anti-doping policy violation involving a non-specified substance is a two-year period of ineligibility.”

Hunter’s suspension is retroactive to Aug. 26, 2016, the date of his provisional suspension, and he’s eligible to return on Aug. 28, 2018. He’s been “disqualified from all competitive results obtained on and subsequent to Aug. 11, 2016, the date his positive sample was collected, including forfeiture of any title, ranking, purse or other compensation,” according to the release.

Hunter, a 33-year-old Canadian, had signed with the UFC after posting a seven-fight winning streak with six first-round stoppages. His only career loss came in his 2010 pro debut.
