UFC anti-doping partner USADA today announced women’s strawweight Jessica Penne has accepted an 18-month suspension for an unspecified steroid.

USADA today reported Penne, 34, tested positive for the presence of an anabolic androgenic steroid of exogenous origin despite initially testing negative for prohibited substances following an out-of-competition urine test conducted on March 20, 2017.

Penne (12-5 MMA, 1-3 UFC) was flagged after a review of her Athlete Biological Passport revealed irregularities in her urine. USADA ordered Penne’s urine sample to be retested, and it was positive for a banned substance. But the result didn’t come back in time to keep her from fighting Danielle Taylor (9-2 MMA, 2-1 UFC) one month later at UFC Fight Night 108.

Penne’s lost the fight to Taylor, which was her third straight UFC defeat.

After being notified of the positive test, Penne told USADA she was prescribed dehydroepiandrosterone (DHEA), an exogenous anabolic agent, by her doctor. After a review of the case, her explanation was accepted by USADA and the Tennessee Athletic Commission, which oversaw UFC Fight Night 108, according to USADA’s release.

Penne’s suspension is retroactive to April 23, the night of the FS1-televised event.

“Under the UFC Anti-Doping Policy, as well as the World Anti-Doping Code, an athlete’s period of ineligibility for using a prohibited substance may be decreased if the athlete lacks significant fault for the anti-doping policy violation,” USADA stated in a press release issued. “In this instance, although Penne was not successful in her attempt to obtain a retroactive or prospective Therapeutic Use Exemption (TUE) for DHEA after her positive test, it was determined that her degree of fault was reduced because her use of the prohibited substance was under the care of a physician. Accordingly, Penne received a corresponding reduction to 18-months from the standard two-year period of ineligibility for a non-Specified Substance under the UFC Anti-Doping Policy.”
