Piotr Hallmann has been suspended nine months following a failed drug test at this past month’s UFC Fight Night 51 event, where he won a “Fight of the Night” bonus.

The Brazilian Athletic Commission (CABMMA) today announced Hallman who co-headlined the UFC Fight Pass-streamed event, tested positive for the anabolic steroid drostanolone.

He’s been suspended nine months, retroactive to the Sept. 13 fight date, and must undergo additional testing before he can be licensed again.

The CABMMA’s full statement:

All athletes from the card were tested for anti-doping control upon arrival at Nilson Nelson Arena to detect anabolic agents, diuretic/other masking agents, stimulants and cannabinoids. Four athletes were randomly selected to also be tested for erythropoietin (EPO) and levels of human growth hormone (Hgh).

The athlete Piotr Hallman failed the test due to presence of anabolic steroid drostanolone. He will be suspended for nine months, reatroactibve to the date of his fight. To be licensed again by CABMMA, he will need to go through new anti-doping control tests.

The Brazilian Athletic Commission (CABMMA) uses WADA accredited lab for its anti-doping control tests.

Hallmann (15-3 MMA, 2-2 UFC), a 27-year-old Polish fighter, suffered a split-decision loss to fellow lightweight Gleison Tibau (30-10 MMA, 15-8 UFC) at UFC Fight Night 51, which took place at Nilson Nelson Gymnasium in Brasilia, Brazil. The loss will remain on his record, and his $50,000 bonus is expected to be revoked.

Hallmann debuted with the UFC in 2013 with a “Submission of the Night” win over Francisco Trinaldo. He subsequently dropped a decision to Al Iaquinta before rebounding with a “Performance of the Night” victory over Yves Edwards.
