The Cardinals placed ORT Brandon Keith (knee) on injured reserve on Tuesday and signed OT D'Anthony Batiste.
Batiste played in five games with the Broncos this season before being released on Oct. 16. He has played in 17 career games with four starts since 2006.
Keith had started all nine games this season.
The way we see it
Jeremy Bridges, an eighth-year veteran, will likely take Keith's place. He has 43 career starts and played well last season against Jared Allen.
