Usain Bolt has been through plenty of drug tests in his time but he was baffled by the most recent request for samples of his blood and urine.
Bolt is currently on trial at the Central Coast Mariners and scored his first two goals for the A-League side last week.
It remains to be seen whether the former Olympic champion will be offered a professional contract to play for the Mariners but Bolt is hopeful of fulfilling his dream of becoming a pro footballer after retiring from track and field last year.
But the 32-year-old could not understand the logic behind a notice to complete an anti-doping test on Monday.
Bolt received an order from the Football Federation of Australia to provide blood and urine in an out-of-competition test under the authority of the Australian Sports Anti-Doping Authority.
“So guys, I’ve retired from track and field looking to become a footballer but look at this,” Bolt said in an Instagram story.
“How am I going to get a drug test today? I’m not even a professional footballer yet. Seriously!
“So I asked the lady, ‘Why am I getting drug tested when I haven’t signed for a club yet?’ and she said they told her I’m an elite athlete so I have to get tested. Okay then.”
The Jamaican is a lifelong Manchester United fan and had been hinting at a move into football for years before training with Norwegian side Stromsgodset earlier this year.
He was then handed a huge opportunity by the Mariners and while he has recently broken his duck for the Australian club, Bolt may be heading elsewhere very soon.
The Sydney Morning Herald reports that the sprinting legend has been offered a professional contract by a southern European club, according to the agent who brought him to Australia.
