Graeme McDowell has been suspended for one tournament and fined $125,000 by LIV Golf after breaching its anti-doping policy due to the use of an over-the-counter Vicks nasal spray containing a banned substance, levo-methamphetamine. The former U.S. Open champion admitted his mistake, stating he took the decongestant to manage severe congestion affecting his sleep without realizing it contained a prohibited substance. As a result, McDowell will miss the upcoming LIV Golf Greenbrier event and his performance and that of his team at the Nashville tournament will be disqualified. This incident marks the first suspension under LIV Golf's anti-doping policy, emphasizing the league's commitment to rigorous enforcement. McDowell expressed regret over not checking the medication list and plans to return to competition at the Chicago event in September. His suspension not only affects him but also his team, Smash GC, which finished poorly at the Nashville event due to the disqualification of their scores.
