INTERNATIONAL: Fresh from their hero’s return to London earlier this week, Team GB has been hit by a doping scandal. The Athletics Integrity Unit has provisionally suspended Britain's Olympic 4x100m relay silver medallist Chijindu Ujah. He joins three other track and field athletes who were suspended during the Olympic Games themselves.

Ujah has been notified by the International World Athletics Federation about the finding. The AIU said in a statement that it had been alerted by the doping control laboratory in Tokyo after the Games that Ujah had returned what’s known as an Adverse Analytical Finding from a test carried out during the Olympics. It listed the prohibited substances Ostarine and S-23. Both are classified by the world anti-doping organisation as “selective androgen receptor modulators”, similar to anabolic steroids.

If the tests are confirmed, Ujah's relay team mates, Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake’s medals will also be at risk.
