The Arizona Cardinals are placing outside linebackers Lorenzo Alexander and Sam Acho and Lorenzo Alexander on injured reserve, ending their seasons.

Alexander suffered a Lisfranc foot sprain and Acho broke his fibula during a 31-7 loss to the New Orleans Saints.

The Cardinals' depth consists primarily of veteran linebackers John Abraham, Matt Shaughnessy and rookie Alex Okafor, a fourth-round draft pick.
