Jamaica’s global superstar Usain Bolt has questioned why he has received a notice for a drugs test from Australia’s Anti-Doping Authority (Asada), saying he is not yet a professional footballer.

The eight-time Olympic sprint champion has been on trial with Central Coast mariners and scored twice on his first start in a friendly on Friday argued that he is not even a professional footballer yet

Bolt who retired from athletics in 2017 says he has been told he is being tested as he is an “elite athlete”.

It is understood that even as a trialist, bolt is officially registered with the club, and is therefore subject to drug testing.

Bolt’s trial period with the a-league club came to an end at the weekend and the mariners now have to decide whether to offer the Jamaican a permanent deal, a further trial period or release him.
