The Arizona Cardinals have placed Darnell Dockett on injured reserve.
In conjunction with the move they announced the signings of Isaac Sopoaga and Ryan McBean. Both received one-year deals.
McBean had been with the Denver Broncos and Pittsburgh Steelers, appearing in 47 games -- 21 starts -- over four seasons.
With the Steelers, he played in one game his rookie year and then spent 2008 on the Broncos practice squad. He played regularly for Denver from 2009-11. In 2012, he missed the season with an ankle injury.
Sopoaga is a 10-year veteran who spent time in Philadelphia and New England in 2013. He had been a San Francisco 49er for the first nine seasons of his career. In 139 games -- 89 starts -- he has 8.5 sacks. He was released by the Patriots in March.
Both will get their chance to join the rotation on the Cardinals' line.
