The Cardinals placed tackle Jeremy Bridges on injured reserve Monday with torn ligaments in his thumb, another blow to the team's depth on the offensive line.
Bridges had entered camp as the starter at right tackle before getting beaten out by rookie Bobby Massie, but he had starting experience at both tackle and guard, something the Cardinals now have little of with Brown and Bridges both done for the year with injuries and Massie and D'Anthony Batiste moving into starting roles.
In Bridges' absence, the Cardinals signed tackle Pat McQuistan to a one-year contract Monday. McQuistan was released by the Cowboys as part of the final roster cuts on Friday. He is entering his seventh year in the NFL after playing with the Saints in 2011 following time with the Dolphins (2010) and Cowboys (2006-09). He played in 10 regular-season games and both postseason contests for the Saints last year after playing in all 16 games, including eight starts, with the Dolphins in 2010.
