Bolton have released Nigeria international Danny Shittu from his contract.
Shittu, 29, joined Bolton from Watford in 2008 for a deal worth in excess of £2 million, but he made only 12 appearances for the club.
A statement on the club's official website read: "Bolton Wanderers have reached an agreement with Danny Shittu to release the defender from his contract at the club with immediate effect. Danny leaves with the club's best wishes."
Shittu was part of the Nigeria squad that competed in this summer's World Cup.
