Colin Healy has left Barnsley after his contract was cancelled by mutual consent.
The Republic of Ireland international only joined Barnsley last summer, but he has failed to hold down a regular place in the side.
The former Sunderland man made ten appearances for Barnsley and spent a spell on loan at Bradford.
Healy has now opted to leave Oakwell to find pastures new.
Meanwhile, Leyton Orient boss Martin Ling has revealed the club just failed in a move to sign Barnsley striker Paul Hayes before the close of the transfer window.
Orient agreed a fee with Barnsley for Hayes, but could not agree terms with the player and Ling admitted it was frustrating to miss out on the striker.
"It's a very frustrating situation, but after calling off the search at 8.30pm, I didn't want to bring a lesser player in on loan for the sake of it before midnight.
"The standard of players we have been in for over the last month shows the levels we are aiming for and the bids we have made show the lengths we are prepared to go to bring them to this football club.
"The loan window opens again next week and my target was always to replace Paul Connor with a better striker - and that criteria still applies. My chairman has backed me financially, but things have not fallen in our favour and the search will continue next week - this has been the most frustrating thing that has happened to me as a manager."
