Anthony Morabito's has headed overseas as he attempts to recover from the bone bruising he is suffering in his troubled left knee.

Fremantle coach Ross Lyon said earlier this month that Morabito was working to his own program as the club continued to try and find solutions to his ongoing knee problems.

Lyon said on Tuesday night that he was aware that Morabito had headed overseas for a short period and they had not discussed his future beyond this year.

"I really gave him permission to go," Lyon told Channel Seven.

"We've worked closely with him. We haven't discussed the future. We just stay in the moment with Anthony. He'll come back refreshed.

"He's certainly increasing his running and his bike riding. So we're optimistic but what the future holds that's really up to Anthony to tell us really what he wants to do."

Morabito is contracted until the end of this season after signing a one-year extension late last year.

He has managed just 26 games since Fremantle secured him with its No.4 draft pick in 2009 and has played only three senior games across 2014 and 2015.

The luckless midfielder has suffered three major knee injuries since joining Fremantle and had minor knee surgery at the start of 2015.
