Nigerian sprinter Nzubechi Grace Nwokocha has been provisionally suspended for the use of banned substances by the Athletics Integrity Unit (AIU).
Nwokocha, 21, ran the anchor leg in Birmingham last month as Nigeria beat England and Jamaica to take gold.
She was part of the winning quartet of Tobi Amusan, Favour Ofili, and Rose Chukwuma who won gold in the 4x100m relay at this year’s Commonwealth Games in Birmingham.
The quartet had set a new African Record of 42.10s to win what was Nigeria’s 11th gold medal in Birmingham and it was a historic moment for the country at the Games.
“The AIU has provisionally suspended Nigerian runner, Nzubechi Grace Nwokocha, for the Presence/Use of Prohibited Substances (Ostarine & Ligandrol) (Article 2.1 and Article 2.2),” the body said in a statement on Twitter.
A provisional suspension means an athlete is temporarily banned from competition before a final decision is taken at a hearing conducted under WADA rules.
Nwokocha qualified for last year’s Tokyo Olympics and also entered the 100m and 200m at the world championships in Eugene this year, reaching the semi-finals in both events.
