Ketlen Vieira has been suspended for six months after testing positive for a banned steroidal substance following her PFL debut loss to Cris Cyborg in August. Vieira said she took medication to aid recovery from a knee injury while she had no active contract, and that she stopped it once the PFL signed her. She maintains there was no intent to violate any rules and believed the gap before her debut would keep her clear of a failed test.
Ketlen Vieira has been handed a six-month suspension after testing positive for a banned steroidal substance following her PFL debut loss to Cris Cyborg in August.
Vieira, a 35-year-old Brazilian who trains with Nova Uniao, said she took medication to help her recover from a knee injury during a period when she had no active contract. She stopped taking it once the PFL signed her, and she believed the gap before her debut would keep her clear of a failed test. She maintains she never intended to violate any rules.
The suspension is a setback for a veteran who entered the promotion with a 16-5-0 record. Vieira, an orthodox fighter, stands five-foot-eight with a 68-inch reach. Her career numbers point to a technical, measured style: she lands 2.71 significant strikes per minute at 40 percent accuracy, and she averages 1.31 takedowns and 0.5 submission attempts per 15 minutes.
The Cyborg bout marked her first appearance under the PFL banner. Cyborg is named in the report only as her opponent that night, and the result of the fight stands as a loss on Vieira's record.
Why it matters
- Vieira's explanation puts a spotlight on how fighters manage injury treatment between contracts, and how long banned substances can remain detectable.
- The six-month ban sidelines her at a stage when she is still establishing herself in a new promotion.
- At 35, a half-year layoff after a knee injury and a debut defeat makes her timeline for a return and a first PFL win more difficult.
Vieira has framed the positive test as a misjudgment about timing rather than an attempt to gain an edge, and her account centers on the absence of a contract when she took the medication. Whether that argument carries any weight beyond the length of the suspension itself is not part of the reported case; the six-month penalty is what stands.
