Daniel Cormier's Former UFC Rival Tests Positive for EPO

2026-07-17 · Daniel Cormier · Player Focus

A UFC title contender who previously faced Daniel Cormier has tested positive for EPO, the UFC announced. The fighter, who competed against Cormier and other top names like Jiri Prochazka, is now under scrutiny for performance-enhancing drug use.

What happened?

The UFC revealed that the fighter, whose name has not been disclosed, tested positive for EPO in a recent out-of-competition drug test. EPO, or erythropoietin, is a banned substance known for boosting endurance by increasing red blood cell production. The fighter has been temporarily suspended pending further investigation.

Why it matters for Daniel Cormier

Daniel Cormier, a former UFC light heavyweight and heavyweight champion, has long been a vocal advocate for clean competition. Cormier faced this fighter earlier in his career, and the positive test raises questions about past performances. Cormier has not yet commented on the situation, but his stance on anti-doping is well-documented.

What comes next?

The UFC and USADA will conduct a full investigation into the positive test. If the fighter is found guilty, he could face a lengthy suspension and potential loss of past earnings. This case adds to the ongoing debate about doping in MMA, a topic Cormier has addressed in the past.

The fighter’s positive test comes at a critical time for the UFC, as the organization continues to enforce strict anti-doping policies. Cormier, now retired, remains a prominent figure in the sport and a respected voice on integrity in competition.
