The Broncos signed veteran OL Ryan Harris on Monday. Harris will replace ORG Chris Kuper on the roster. Kuper broke his lower leg, head coach John Fox announced.
Harris started 34 games and appeared in 46 from 2007-10 with the Broncos. He spent the 2011 training camp with the Eagles before being cut and has not played this season.
Kuper started all 16 games this season. He has missed only two starts in the past four seasons. Russ Hochstein is likely to take Kuper's place on the O-line. The veteran reserve has played in 15 games this year with no starts. He started six games last season and 10 in 2009.
Harris will provide depth on the O-line. The Broncos host the Steelers in the wild-card round of the playoffs.
