Former Australian international goalkeeper Mark Bosnich is expected to be fit for the final match of his short-term A-League contract, his Central Coast Mariners club said on Tuesday.

It was initially feared that Bosnich's stint with the Mariners was over after the former Aston Villa and Manchester United keeper sustained a hamstring injury early in his side's 4-1 win over Perth Glory last Friday.

But Bosnich, 36, said the news from doctors was positive, indicating he had strained his left hamstring muscle rather than torn it. He is expected to be available for the game against Wellington Phoenix in a fortnight, his last scheduled game in the seven-week contract.

In his four A-League matches, Bosnich has played a key role in the Mariners' unbeaten run.
