THE FUTURE of Fremantle midfielder Michael Barlow is still in limbo with less than 24 hours remaining in the NAB AFL Trade Period. 

Barlow, 28, is out of contract and had been given no assurances of continuing at Fremantle in 2017 given the Dockers' move to rejuvenate their list. 

Barlow played just 13 matches this season and was dropped to the WAFL after round seven.

But he returned in round 10 and produced some sparkling mid-season form in an unfamiliar run-with role in the midfield. He then suffered a season-ending shoulder injury in round 17 that required surgery. 

He still finished eighth in the Dockers' best and fairest despite missing nine games but has been unsure of his future for quite some time.

Barlow's manager Marty Pask told NAB AFL Trade Radio on Wednesday that the midfielder was a victim of circumstance and was still in limbo with just one day to go in the trade period.     

"There is some interest in him, no doubt about that," Pask said.

"But unfortunately some clubs might not be able to do anything at this point in time because they either have to wait for another player to move out or find out what other picks they might have or what the list spots look like. 

"All these sorts of variables are taking place at the moment. So at the moment it's just waiting for a couple of these decisions and things to fall and then hopefully something still might be able to be done in the next 24 hours and Mick could find himself on a list elsewhere.

"But still there's got to be a conversation with Fremantle and work out what lies there as well before you worry about anything else.

"We're still hopeful that something might fall within the last 24 hours."

Hayden Ballantyne is contracted to the Dockers for 2017 and appears set to stay at Fremantle despite a desire to move to West Coast.

Unrestricted free agent Zac Clarke is still negotiating a new contract with the Dockers.
