LAUSANNE, Switzerland – Grenadian sprinter Bralon Taplin has lost his appeal against a four-year ban for dodging a doping test, which means he will miss the Tokyo Olympics if it comes off next year, as well as the next two World Championships.

After saying that it was “comfortably satisfied” that the athlete purposely evaded testing, the Court of Arbitration for Sport (CAS) said in a statement issued here on Tuesday that the ban, imposed by the Caribbean Regional Anti-Doping Organization (RADO) last year, would remain in place until September 2023.

The ruling by CAS judge Hugh Fraser came just over a year after the incident that sparked the ban.

Bralon Taplin’s ban for dodging a doping test will remain in place until September 2023.

After winning the 400m at the Grenada Invitational Athletics Competition on April 13, 2019, Taplin left the stadium without completing doping control, despite being informed that he was to undergo a drugs test.

The 28-year-old appealed the Caribbean RADO’s decision at the CAS, claiming he had not been properly notified that he had been selected for the doping control test.

However, CAS said, Taplin was told by a chaperone from the Grenada National Anti-Doping Organisation (Grenada NADO) during trackside media interviews that he was required to give a sample, yet he left the stadium and took an early flight out of the country the following day.

“The sole arbitrator found that the evidence given by the athlete that he was never approached, followed or accompanied by anyone from the Grenada NADO to be implausible,” the CAS press release said.
