Jobe Wheelhouse will take time away from football to ponder his future after parting company with the Newcastle Jets.
The club advised Wheelhouse, 27, he would not be offered a new deal for next season, and the Newcastle-born player decided to leave immediately.
"It goes without saying that I am disappointed I won't be at the Jets anymore," Wheelhouse said.
"Over the last six-to-12 months my head hasn't been in it like it should be, and this will now give me a chance to get away and plan my future.
"There is no point being at a place when my heart isn't in it and the last thing I want to do is let down my team-mates.
"I haven't ruled out playing in the future, I just need time to sort out what I want to do.
"I am good mates with all of the boys and I wish them only the best for the future.
"Hopefully they will make the six and go deep into the finals this year."
Jets chief executive Robbie Middleby said the club respected Wheelhouse's honesty and thanked him for his service, which dated back to 2003.
"This hasn't been an easy process and we hoped Jobe would play out the remainder of the season," he said.
"We have worked through this process to ensure the best outcome for Jobe's future, which is why we have agreed to his request.
"We thank Jobe for his contribution to the club and wish him all the best in the future."
