A UFC heavyweight and featherweight were both facing pretty identical issues with USADA, and it turns out that they have both accepted the same two-year suspensions after a multi-day arbitration hearing.
Ruslan Magomedov (14-1, 3-0 UFC) and Zubaira Tukhugov (18-4, 3-1 UFC) both tested positive for ostarine from out-competition samples collected way back on September 7th, 2016. Tukhugov popped for it again in an October 29th out-of-competition test as well, but USADA treated them as the same failure for the purposes of their investigation.
Both men blamed tainted supplement for their failures and denied directly using the substance, but USADA couldn’t independently confirm that fact.
