The Arizona Cardinals have announced today that they have placed offensive tackle Brandon Keith on injured reserve with a third degree tear in his right hamstring, which he suffered in the first quarter of Sunday's game. Keith, who has started all nine games at right tackle this year, will likely be replaced by veteran lineman Jeremy Bridges.
OL D'Anthony Batiste has been signed to the practice squad to fill Keith's spot on the 53-man roster.
The Cardinals also announced that they have signed RB Alfonso Smith to the practice squad to aid the ailing running back corps. WR Ed Gant was waived to make room for the signing.
