The United States Anti-Doping Agency (USADA) clarified today that former UFC fighter Ivan Shtyrkov (15-0-1) has been suspended for two years for two failed out-of-competition drug tests.
Specifically, Shtyrkov’s previous scheduled bout with Devin Clark at UFC on ESPN+ 7 was cancelled when two urine tests came back “atypical.” He then subsequently signed with Rizin FF.
Collected on March 27 and April 3, the samples contained the steroid Boldenone and its metabolite 5β-androst-1-en-17β-ol-3-one. Boldenone is in the anabolic class, is prohibited at all times and carries a two-year suspension on an initial conviction.
Shtyrkov’s suspension is retroactive to the date of the of earliest sample collection which was March 27, yet he is currently scheduled to face Hoon Kim July 28 at Rizin FF 17 in Saitama, Japan.
