On 15 November 2018, FINA conducted an out-of-competition doping control test on the swimmer, Conor Dwyer (USA). On 27 November 2018 and on 20 December 2018, USADA also conducted out-of-competition doping control tests on the same swimmer. The three samples collected from the athlete were tested positive for an anabolic agent of exogenous origin (Class S.1.1B Endogenous Anabolic Androgenic Steroids).

The proceedings were consolidated and the American Arbitration Association Panel decided to impose on the athlete a period of twenty (20) months’ ineligibility, starting on the date of his provisional suspension, 21 December 2018, and ending at the conclusion of 20 August 2020, for his first anti-doping rule violation.

Furthermore, all results achieved by the athlete on or after 15 November 2018 were disqualified together with the consequences thereof (forfeiture of medals/prizes, reimbursement of prize money).
