Sprinter Bracy-Williams banned

Marvin Bracy-Williams

Former world 100m silver medallist Marvin Bracy-Williams has been given a 45-month ban for doping offences after a whistleblower triggered an investigation.
The 31-year-old American sprinter was runner-up at the 2022 World Championships at Eugene in Oregon.
He was also part of the USA men’s 4x100m relay team that won silver, which means Great Britain are set to be upgraded to silver from bronze.
Bracy-Williams was provisionally suspended in February 2024 after testing positive for anabolic agent testosterone. The United States Anti-Doping Organisation (Usada) said it received a tip from a whistleblower.
Bracy-Williams, who has not competed since 2023, initially tried to tamper with the investigation and also breached the whereabouts rules where athletes must let officials know where they will be.
But he later admitted his violations and also provided “substantial assistance” to the investigation, said Usada, which carried out the investigation with the Athletics Integrity Unit (AIU) and US Drug Enforcement Administration.
“This case is an example of the importance of cooperation between like-minded organisations and law enforcement agencies when it comes to eradicating organised doping schemes,” said Usada chief Travis Tygart.
