CJ Ujah: Great Britain lose Tokyo Olympics relay medal after doping violation

Great Britain have been stripped of the silver medal won in the 4x100m relay at last summer's Tokyo Olympics after team member CJ Ujah was found to have committed a doping violation.

The British team finished second to Italy by one-hundredth of a second.

Ujah tested positive for ostarine and S-23 after the event on 6 August.

The 27-year-old says he «unknowingly consumed a contaminated substance» and the situation is one he «will regret for the rest of my life».
