The Cardinals placed starting right guard Evan Mathis on injured reserve and signed guard/tackle Ulrick John off Miami’s practice squad.
Mathis has been dealing with an ankle injury for most of the season and left Thursday night's game against the 49ers because of an ankle injury. He’s the third key player the Cardinals have placed on injured reserve in the last week. Running back Chris Johnson and defensive back Tyvon Branch were put on the list after suffering injuries on Oct. 2 against the Rams. They both needed hernia surgery.
The Cardinals can bring one player off injured reserve during the season.
