The Jamaican 100m world record holder has been training with the Gosford club in the hope of impressing coach Mike Mulvey enough to land a contract.

He's struggled with his football fitness though and underwhelmed in his first trial game against a local select side last weekend.

Today the club revealed Bolt will leave the country tomorrow to fulfil commercial obligations overseas. He's reportedly headed for France to hook up with a champagne company.

A club statement added: "After completing his first three weeks of training with the Central Coast Mariners, the club wishes to advise that Usain Bolt will be abroad from Sunday, 9 September to Sunday, 16 September for a previously planned commitment.

"This commitment was agreed between Usain Bolt and the Central Coast Mariners before his training period commenced with the club."
