CJ Ujah, a member of the British silver medal winning men’s 4x100m relay team at the Tokyo Olympics, has been provisionally suspended for an anti-doping violation.
Ujah ran the first leg in the final, with the team being completed by Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake who were only passed by Italy in the closing stages.
The quartet was eventually defeated by just a hundredth of a second, with Canada back in third place and China just outside the medal positions.
Ujah was one of four athletes named in a statement from the Athletics Integrity Unit on Thursday, along with Bahrain 1500m runner Sadik Mikhou, Georgian shot putter Benik Abramyan and Kenyan sprinter Mark Otieno Odhiambo.
The 27-year-old’s anti-doping test would have shown the “presence/use of a banned substance”, namely Ostarine and S-23.
