The Barking-born defender, who was capped twice for England, became Gillingham’s highest-profile signing ahead of the 2016/17 League One season when he joined the club on July 21.
Konchesky, who has made over 500 professional appearances during a career which spans 19 years, signed a one-year deal at the MEMS Priestfield Stadium.
He became Charlton Athletic’s youngest-ever debutant when he played against Oxford United in August 1997, aged 16 years and 93 days. After a four-month loan spell at Tottenham Hotspur in 2003 and over 150 appearances for the Addicks, Konchesky left The Valley for West Ham in a £1.5m transfer in July 2005.
He scored in the Hammers’ FA Cup Final defeat to Liverpool in May 2006, before joining their Premier League rivals Fulham 14 months later. Konchesky started 122 games during his three years at Craven Cottage, including the Europa League Final in 2010.
Future England manager Roy Hodgson signed him for Liverpool in August 2010, and he went on to make 18 appearances for the famous Merseyside club. Following a loan spell with Nottingham Forest between January and April 2011, Konchesky joined then-Championship club Leicester City, and played in their second tier title-winning team of 2013/14.
Most recently, he made 34 appearances for Championship side QPR during a loan spell last season.
Konchesky made 15 appearances for the England under-21 team, and was capped by the senior squad in friendlies against Australia (February 2003) and Argentina (November 2005).
