Daniel Cormier's Former UFC Rival Volkan Oezdemir Fails Drug Test

Former UFC light heavyweight title challenger Volkan Oezdemir has been suspended after testing positive for erythropoietin (EPO) in out-of-competition drug tests conducted on February 16 and March 5, 2026. Oezdemir, who famously fought Daniel Cormier for the UFC light heavyweight title in 2018, admitted to the violation and will be ineligible to compete until June 17, 2027.

What happened?

Volkan Oezdemir, known as 'No Time,' tested positive for EPO in both urine and blood samples collected in Le Mouret, Switzerland. The UFC's drug testing program, administered by Combat Sports Anti-Doping (CSAD), confirmed the violation. Oezdemir publicly acknowledged the infraction, stating it was the 'biggest mistake of my life.'

Why it matters for Daniel Cormier

Oezdemir's failed drug test casts a shadow over his career, including his high-profile title fight against Daniel Cormier at UFC 220 in January 2018. Cormier, a two-division UFC champion, defeated Oezdemir via second-round TKO to retain his light heavyweight title. The revelation of Oezdemir's doping violation may lead to renewed scrutiny of that bout and other past performances.

What comes next?

Oezdemir's suspension will last until June 17, 2027, effectively sidelining him for over a year. The Swiss striker, currently ranked No. 8 at 205 pounds, last competed in October 2025, securing a knockout victory over Alonzo Menifield at UFC Qatar. His career record stands at 21-8, with notable wins over Jiri Prochazka and Ovince Saint Preux.

Oezdemir's admission of guilt and cooperation with authorities may mitigate further penalties. However, the incident tarnishes his legacy and raises questions about the integrity of his past victories. For Daniel Cormier, this development serves as a reminder of the ongoing challenges in maintaining a clean sport within the UFC.
