With offensive lineman Hugh Thornton out for the foreseeable future, the Indianapolis Colts added depth at guard with signing of Harland Gunn on Friday, the team announced.

The 6-foot-2, 310-pound Gunn appeared in 13 games over the last two seasons with the Atlanta Falcons, including a start against the New York Giants last year. He was with the New England Patriots in training camp this summer, but was waived Aug. 6.

An undrafted free agent out of the University of Miami, Gunn spent 2012 training camp with the Dallas Cowboys, before being waived. Gunn then spent 11 weeks on the New Orleans Saints practice squad before the Falcons signed him to the active roster in November of 2012.

Gunn becomes the latest former Hurricane to join the Colts, including running back Frank Gore, wide receivers Andre Johnson and Phillip Dorsett and tight end Erik Swoope.

He'll compete with veterans Joe Reitz and David Arkin for time as a backup guard. Head coach Chuck Pagano announced Thursday that Thornton is "week-to-week" after suffering a knee injury in practice Wednesday.
