Histon defender Ollie Cleaver has decided, at the age of 19, that he no longer wants to be a footballer.
Boss David Livermore told BBC Radio Cambridgeshire the former Forest Green right-back will take unpaid leave so he can consider his options fully.
He said: "It was a bit of a surprise. Ollie came to me a few weeks back. He didn't feel football was for him.
"It's a brave decision he's made. It's great honesty from the lad. I think he needs to be commended for that."
Cleaver has made seven first-team appearances for the Blue Square Bet North side this season after impressing in the reserves last term.
"We've left it open for him to come back," added Livermore. "If he still decides football is not for him we'll fully honour his decision.
"He assured me it wasn't a decision he took lightly. I have asked him to have a little think and if he feels the same I will respect his decision.
"Anyone that doesn't want to be at the football club is welcome to leave."
