British sprinter CJ Ujah has been suspended from competition after testing positive for a banned substance.
Ujah, 27, was part of Team GB men’s 4x100m relay team which won silver at the Tokyo 2020 Olympics this month.
He has been provisionally suspended, said the Athletics Integrity Unit (AIU).
The AIU said a test showed the “presence/use of a prohibited substance (Ostarine and S-23).”
A UK Athletics spokesperson said the governing body does not comment on ongoing processes.
Ujah, who has yet to comment, won the 100m at the British Championships in June.
