Boxer Robbie Turley has been suspended from all sport for one year following an Anti-Doping Rule Violation (ADRV).
The 31-year-old had furosemide in his system on April 7 last year when he won the vacant Commonwealth super-bantamweight title with a ninth-round stoppage of Bobby Jenkinson in Newport.
Furosemide is listed under section S5 of the WADA 2017 Prohibited List as a Diuretic and Masking Agent and is banned at all times.
Turley was charged with, and admitted to, the ADRV in violation of ADR Article 2.1. - "Presence of a Prohibited Substance or its Metabolites or Markers in a Player's Sample."
The 31-year-old provided evidence to suggest he inadvertently took furosemide, having intended to take ibuprofen.
In determining the appropriate sanction, the NADP Tribunal that heard the matter concluded Mr Turley was at 'No Significant Fault or Negligence' for the ADRV pursuant to ADR Article 10.5.1(a).
Nicole Sapstead, UKAD's Chief Executive, said: "It is every athlete's individual responsibility to monitor and control what substances enter their body.
"We hope cases such as Mr Turley's serve as a reminder to all other athletes to check what they are ingesting and ensure it is in line with the WADA Prohibited List."
