Motherwell have announced that David Turnbull is to remain with the Scottish Premiership club after a potential move to Celtic fell through.
An agreement with the champions had been reached but an issue was discovered during Turnbull's medical, which will require an operation.
Motherwell have confirmed that he'll now stay at Fir Park rather than making the switch to Neil Lennon's side.
“David Turnbull is to remain a Motherwell player, with a proposed move to Celtic FC no longer taking place.
"An agreement was reached with the Glasgow club on 12 June, subject to the player agreeing personal terms, which he did, and undergoing a medical. During that medical process, an issue was identified that will require David to have immediate preventative surgery and subsequent rehabilitation.
“Celtic were still keen to sign the player despite this matter arising. But having presented revised transfer terms to Motherwell, the clubs could not reach an agreement.
“David will now remain at Fir Park and will shortly have an operation which will rule him out of any football for an extended period, the exact length to be determined following surgery.
“We will give David all the support he needs during this process. We wish him the best with his procedure and rehabilitation, and look forward to watching him play in claret and amber again in the near future.”
Motherwell's David Turnbull.
Celtic say they were still keen to sign the Scottish Young Player of the Year but terms could not be agreed.
“It is unfortunate that we were not able to proceed with the transfer of David to Celtic, having agreed a significant fee with Motherwell and reaching agreement with the player.
It is regrettable that David will be out of action for a considerable length of time and, clearly, these circumstances are totally outwith the club’s control. We did everything we could to find a solution.
“We would like to thank David and his representatives for the professionalism they have shown throughout. We also thank Motherwell FC for the way they have handled this process.
“We wish David all the very best with the operation and every success for the future.”
