Violation of anti-doping regulations results in a 6-month suspension
American professional golfer Trey Mullinax has been suspended from competing in PGA Tour events for six months due to a violation of the PGA Tour’s anti-doping program. Mullinax will be eligible to compete in PGA Tour tournaments again starting on January 16, 2027.
According to information released by the PGA Tour on July 29, 2026, and reported by CBS Sports, samples taken from Mullinax tested positive for a performance-enhancing substance prohibited by the World Anti-Doping Agency (WADA). The specific name of the substance and the medical condition it is intended to treat have not been disclosed.
Medications taken for conditions diagnosed during university years
Mulnix issued a statement explaining that he recently used medication to treat a condition first diagnosed during his college years, but he did not obtain prior approval as required by the PGA Tour’s anti-doping policy.
He accepted the disciplinary action, stating that he was responsible for verifying the relevant regulations and the drugs he was taking. However, he emphasized that he did not use the substance with the intention of enhancing his performance.
According to a report by Golf Monthly, Murnane cooperated with the investigation and accepted the six-month suspension. He stated that he will take this incident as a lesson and hopes to return to the competition in 2027.
PGA Tour’s disclaimer regarding therapeutic use
Prohibited substances must be approved before use
The PGA Tour’s 2026 anti-doping program manual provides a Therapeutic Use Exemption (TUE) application process for athletes who require prohibited substances for medical treatment. In principle, athletes must obtain approval before using prohibited substances, and must submit relevant medical documentation at least 30 days before the tournament they are scheduled to participate in.
The regulations stipulate that the responsibility for ensuring that prohibited substances do not enter an athlete’s body lies with the athlete themselves. Even if there is no evidence of intent or an attempt to enhance performance, a violation of the regulations can occur solely through the use or detection of a prohibited substance.
Urine and blood sample testing available
The PGA Tour can collect urine or blood samples from players subject to testing, regardless of whether they have been given prior notification. The first violation of the anti-doping regulations can result in a suspension of up to one year. Depending on the circumstances, penalties may also include disqualification, cancellation of results, forfeiture of prize money and points, or fines.
2022 Babasol Championship Winner
Mullinax, born in 1992, attended the University of Alabama before turning professional in 2014. According to his official PGA Tour profile, he has a total of 1 professional win.
He won his first PGA Tour title in 2022, securing a birdie on the final hole of the Barbasol Championship. In 2026, he participated in two PGA Tour events and one Korn Ferry Tour event, but failed to make the cut in all of them. His last appearance was at the Zurich Classic in April.
Due to this suspension, Mullinax will be unable to participate in any PGA Tour events or related activities for the remainder of 2026. His eligibility to return is January 16, 2027.
