Britain’s Olympic 4×100-metre relay silver medallist Chijindu ‘CJ’ Ujah has been provisionally suspended for allegedly breaching anti-doping rules at the Tokyo Games, the Athletics Integrity Unit has reported.

Three other track and field athletes who were suspended during the Games – Moroccan-born Bahraini 1500-metre runner Sadik Mikhou, Georgian shot putter Benik Abramyan and Kenyan sprinter Mark Otieno Odhiambo – were also listed.

The AIU said in a statement on Thursday that it had been notified by the doping control laboratory in Tokyo after the Games that Ujah had returned an Adverse Analytical Finding from a test carried out during the Olympics.

It listed the prohibited substances detected as Ostarine and S-23, both classified by world anti-doping organisation WADA as a selective androgen receptor modulator (SARM) with effects similar to anabolic steroids.

Ujah’s relay teammates were Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake. Their medals will also be at risk if the positive is confirmed.

The AIU said it had worked closely with the International Testing Agency during the Games and provided the intelligence to carry out specific target testing on two of the four athletes, without specifying which.

“The AIU now awaits the conclusion of the ITA proceedings against the above athletes, which will determine whether any anti-doping rule violations have been committed and what consequences [if any] should be imposed in relation to the Olympic Games,” it added.

It added that it had been notified of another AAF for Odhiambo in a sample collected in South Africa on June 24, before the Games started.

The Anti-Doping Agency of Kenya has handed over the case management responsibility to the AIU.

Odhiambo, a 100-metre sprinter, was suspended before the qualifying heats in Tokyo.

Mikhou was suspended for receiving a blood transfusion during the Games.

Abramyan failed an out of competition dope test for steroids in Tokyo.
