Team GB sprinter CJ Ujah has insisted he is “not a cheat” despite testing positive for two banned substances after winning silver in the 4x100m relay in Tokyo.
Ujah and his three teammates are facing the prospect of being stripped of their Olympic medals if the case against him is proven.
The 27-year-old said in a statement: “It’s taken me a few days to process the information I received on Thursday shortly before it was made public
“I am completely shocked and devastated by this news.
“To be absolutely clear, I am not a cheat and I have never and would never knowingly take a banned substance.
“I love my sport and I know my responsibilities both as an athlete and as a team-mate.”
The International Testing Agency said on Thursday that two prohibited muscle-building substances – ostarine and S-23 – were found in his sample that was collected after he competed in the Olympic final.
