Bellator 179 took place last month at the SSE Arena in London, England and all of the in-competition drug test results from the event have came back clean.
Mohegan Tribe Department of Athletic Regulations Director Mike Mazzulli confirmed the drug test results to The MMA Report on Tuesday after they were requested.
Bellator 179 took place on May 19 and was headlined by Rory MacDonald winning his promotional debut by submission against Paul Daley in the second round. The victory for MacDonald secured him a title shot in the Bellator welterweight division and he is expected to fight for the Bellator 170 pound title later this year against the winner of the upcoming title fight between champion Douglas Lima and Lorenz Larkin.
