AFC Wimbledon defender Andy Frampton has announced his retirement following an injury-hit season.
The 35-year-old centre-back has not featured since November and had an operation on a long-standing ankle injury in January.
Frampton joined the Dons in 2013 and scored five goals in 39 appearances.
"I am gutted, but it is a decision I have made with my family and I believe it is the right time," he told the Wimbledon website.
"Not so long ago I did a session on my own as part of my rehabilitation. It was not a particularly heavy session but for three days afterwards I had a bad reaction."
Frampton came through the youth ranks at Crystal Palace and made his senior debut in 1999.
He subsequently had spells at Brentford, Millwall and Gillingham and spent time on loan at Leyton Orient and Swindon.
"I was not the most skilful player or the quickest, but I played with my heart and every challenge and every pass meant the world to me," he added.
"It has been a privilege to be one of those people lucky enough to have played football for a living."
