Indianapolis, IN -- (Sports Network) - Indianapolis Colts guard Ryan Lilja will remain sidelined because of a knee injury that kept him on the physically unable to perform list for the first 11 games of the year.

The Colts said the fifth-year player will undergo surgery in an attempt to correct the injury.

Lilja started all 16 games at left guard last season after a knee injury limited him to 11 games with five starts in 2006. He also started all 16 games in 2005.

The Colts claimed the Kansas State product off waivers from Kansas City in September 2004. He has played 50 games with Indianapolis, starting 43.
