Trey Mullinax tested positive for a substance banned under the PGA Tour's anti-doping policy and received a six-month suspension announced on July 29, 2026 [1, 2, 3]. The 34-year-old American is eligible to return to competition on January 16, 2027 [1, 2, 3].
Mullinax cooperated fully with the Tour’s investigation and accepted the penalty without appeal [1, 2, 3]. He said, “I take full responsibility for what happened. At the end of the day, it is my responsibility to understand and follow the PGA Tour's anti-doping policy and all of its rules and regulations. I failed to do that, and that is on me.”
The medication that triggered the violation was used to treat a medical condition Mullinax was diagnosed with in college. He admitted he did not seek prior approval from the PGA Tour before using the drug, violating the Tour’s rules [1, 2, 3]. Mullinax emphasized, “I want to be absolutely clear -- I have never taken any substance with the intention of gaining a competitive advantage.”
Mullinax has struggled with form and health since his only PGA Tour victory at the 2022 Barbasol Championship [1, 2, 3]. In 2026, he made just two PGA Tour starts and missed the cut in both events [1, 2]. He also played once on the Korn Ferry Tour this year. His last competitive appearance was at the Zurich Classic of New Orleans in April 2026 [3]. Mullinax failed to secure a full-time PGA Tour card through Qualifying School earlier this year [3].
After the suspension was announced, Mullinax said, “I accept the consequences of my actions and will use this experience as a lesson. Golf has given me so much, and I never want one mistake to define the respect I have for the game or for the people who support me.”
Mullinax’s suspension ends when he becomes eligible to compete again on January 16, 2027 [1, 2, 3].
