British sprinter Chijindu “CJ” Ujah has been suspended for an anti-doping violation which could see Great Britain stripped of an Olympic silver medal.
- Great Britain came second in the 4x100m relay by 0.01 seconds from Italy
- British 100m champion CJ Ujah ran the lead-off leg
- Ujah’s positive test, if proven, will see Britain lose its silver medal
The 27-year-old was the lead-off runner in the British 4x100m relay team that won silver behind Italy in Tokyo.
Ujah, the British champion over 100m, tested positive for ostarine and S-23, both of which are listed as prohibited substances by the World Anti-Doping Agency.
He has been provisionally suspended, according to the Athletics Integrity Unit.
If proven, the entire team, consisting of Ujah, Nethaneel Mitchell-Blake, Richard Kilty and Zharnel Hughes would be stripped of their medals.
Athletics anti-doping rules state that in the event of one member testing positive, the entire team would forfeit their position.
Canada would see their bronze medal upgraded to silver, while China would be upgraded from fourth to bronze.
The Great Britain and Northern Ireland quartet were edged out of gold by 0.01 seconds by Italy on the track in Tokyo after Mitchell-Blake was dramatically overhauled by Filippo Tortu.
The result would be a huge scandal for the British team, which has previously seen Linford Christie and Dwayne Chambers banned for doping offences, but not at an Olympics.
If proven, Ujah would be the fourth athlete to have tested positive for a banned substance at the Olympic Games.
Bahrain’s Sadik Mikhou, who ran the 1,500m, shot putter Benik Abramyan of Georgia and Kenyan sprinter Mark Otieno Odhiambo were all provisionally suspended following adverse tests.
