Colts release Gosder Cherilus

— -- INDIANAPOLIS -- The Colts have released starting right tackle Gosder Cherilus, the team announced Sunday.

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

Cherilus failed to live up to his contract despite starting 29 games the past two seasons. He 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.

The Colts had serious doubts about Cherilus' health, and  Jack Mewhort, who started 13 games at left guard as a rookie last season, worked exclusively with the first unit at right tackle during all offseason activities.
