Cambridge United midfielder Adam Miller has retired from football after two years spent trying to regain fitness following an ankle injury.
Miller joined Cambridge from Gillingham in June 2010 on a three-year contract.
However, he was injured in a game against Eastbourne two months later and subsequently underwent four operations.
"I'm disappointed I was only able to play a few games for Cambridge and I'm devastated this is the end of my career," the 30-year-old said.
"Everyone at the club has been really supportive, both emotionally and in terms of everything we've had to do physically.
"I know they have gone above and beyond what other clubs would do to help."
Miller began his career as a trainee at Ipswich and played for a number of other clubs including Aldershot, QPR and Stevenage during his career.
He has been invited to attend Cambridge's home game against AFC Telford United on Saturday so he can bid farewell to supporters.
"At all times we've had Adam's best interests in mind and the club has acted properly and professionally," said manager Jez George.
"It has been a frustrating situation but Adam has been very patient and it's disappointing for everyone concerned that this is the end to his career."
