Englewood, CO (SportsNetwork.com) - Denver Broncos Pro Bowl left tackle Ryan Clady was placed on season-ending injured reserve Friday.

Clady, who earned his fourth career Pro Bowl nod last season, tore the anterior cruciate ligament in his left knee during Wednesday's OTA session.

With Clady gone for the season, the Broncos signed veteran offensive lineman Ryan Harris, who spent his first four NFL seasons in Denver.

The 30-year-old Harris started 15 games at right tackle last season for Kansas City. Before that, he spent two years in Houston with current Broncos coach Gary Kubiak.

Harris has played right tackle throughout his career, which leaves rookie Ty Sambrailo and veteran Chris Clark among the in-house replacements for Clady.

Clady, Denver's longest tenured player, has started all 98 games he's appeared in during his seven seasons with the club. The 2008 first-round pick was also named to the Pro Bowl following the 2009, 2011 and 2012 seasons.
