The Indianapolis Colts have released Gosder Cherilus, who was their starting right tackle.

He was one of the main free-agent acquisitions by the Colts in 2013, when Cherilus signed a five-year, $34 million contract.

Cherilus battled knee, shoulder and groin problems last season before eventually being placed on injured reserve prior to the playoffs.

The 31-year-old Cherilus had offseason knee surgery, which kept him from taking part in organized team activities, including a mandatory three-day minicamp in June.

Indianapolis tried to restructure Cherilus' contract before cutting him, according to an NFL source. Cherilus' agent Greg Diulus also acknowledged contract negotiations when discussing his client's release.
