A knee injury has forced former Brighton, Celtic and Bristol Rovers defender Adam Virgo to retire at the age of 30.
Virgo had been without a club since his release by Rovers in the summer after an injury-hit two-year spell at the club. His last game was against AFC Wimbledon in October 2012.
Virgo came through the youth ranks at Brighton and went on to make 158 appearances across two spells. He scored a vital play-off goal as the Seagulls won promotion to the Championship in 2004.
The central defender, who could also play up front, joined Celtic in a ?1.5million deal the following summer. Virgo rejoined Brighton in 2008 before moving to Yeovil and then Bristol Rovers. He also had loan spells with Exeter, Coventry and Colchester during his 12-year career.
Virgo featured for Crawley in a pre-season friendly this summer but his knee problem prevented him from finding a new club.
He posted on his Twitter account: "Overwhelmed with messages from Ex team mates and supporters thanks for the memories #beenemotional."
