Peterborough striker Aaron Mclean has handed in a transfer request at London Road.
The Championship side have reluctantly accepted the request and agreed to let him leave when the transfer window reopens.
Mclean has cited being dropped for the game at Newcastle last month as the reason for his decision to ask for a transfer.
"I have been with the club for three years now and after the £2million offer from Wolverhampton Wanderers was rejected, I got my head down and helped us get promoted to the Championship," Mclean told the club's official website.
"I was made club captain and then dropped for the biggest game of my career at Newcastle United. After the game I spoke with the chairman about how upset I was.
"I did not hand in a transfer request at this time as he asked me to back him. I decided again to try and get on with things as the chairman, staff and supporters have been very dear to my heart, but I just can't get over the way I was treated and now feel these factors, my age and my family commitments make it the right time to move clubs."
