PGA Tour Suspends Trey Mullinax for Six Months Due to Prohibited Substance; Golfer Cites Medication.

Mullinax became the ninth golfer suspended under the PGA Tour anti-doping program since it began testing in 2008, and the first to face suspension since Byeong Hun An in October 2023.
Mullinax’s 2026 season was unusually sparse, with only three competitive appearances (two on the PGA Tour and one on the Korn Ferry Tour) and all three events resulting in missed cuts.
The substance involved in the positive test has not been publicly disclosed by the PGA Tour, with outlets noting the substance remains a mystery.
Mullinax publicly attributed the failed test to taking a medication to treat a college-diagnosed condition without Tour approval, saying, "My lack of knowledge is not an excuse," and emphasizing that he has never taken a substance to gain a competitive advantage.
The PGA Tour has upheld a six-month suspension for Trey Mullinax after he tested positive for a substance banned by the World Anti-Doping Agency. Mullinax will not be eligible to return to competition until January 16, 2027, effectively wiping out his entire 2026 season.
Mullinax accepted the ban and cooperated fully with the Tour. He said the positive test came from a prescription medication for a condition diagnosed in college — taken without Tour approval. "My lack of knowledge is not an excuse," he said publicly, adding that he never intended to gain a competitive advantage.
Mullinax becomes the ninth golfer suspended under the PGA Tour's anti-doping program, which launched in 2008. He is also the first player to face a suspension since Byeong Hun An was banned in October 2023. Formal, publicly disclosed doping bans remain rare in professional golf compared to other sports.
The Tour aligned its policy with WADA standards. Under those rules, players must get approval — called a therapeutic-use exemption — before using any banned medication, even one prescribed by a doctor. Mullinax acknowledged he did not follow that step.
The PGA Tour has not named the substance that triggered Mullinax's positive test. Multiple outlets noted the substance remains a mystery. The Tour's policy does not require public disclosure of what was found, only that a violation occurred and a suspension was issued.
Mullinax's own statement pointed to a prescription drug he had used since college. He said he did not know the medication was on the banned list. He took full responsibility for failing to check the drug against Tour rules before using it.
Before the suspension was announced, Mullinax had already struggled in 2026. He made just three competitive starts — two on the PGA Tour and one on the Korn Ferry Tour. He missed the cut in all three events. The ban now ends any chance of a 2026 comeback.
Mullinax's world ranking sits outside the top 100. That makes the timing especially costly. A full season off the course will make it harder to rebuild ranking points and secure status for 2027. He won the 2022 Barbasol Championship and has two Korn Ferry Tour titles to his name.
Despite the ban, Mullinax has said he plans to compete again in 2027. His eligibility date of January 16, 2027 gives him a narrow window to prepare before the new season gets underway. He framed his public statement as an acceptance of consequences, not a protest.
The case adds Mullinax to a short list of golfers who have faced formal anti-doping consequences on Tour. With only nine suspensions across nearly 17 years of testing, the program's violations remain uncommon — but each one draws significant attention when it does occur.
