The Arizona Cardinals' rash of injuries to outside linebackers has continued.
Wednesday morning, the team placed rookie OLB Alex Okafor on injured reserve and elevated linebacker Kenny Demens to the 53-man active roster from the practice squad.
Okafor, a 2013 fourth-round pick out of Texas, suffered a torn biceps tendon injury in a loss to New Orleans last Sunday.
Demens, an undrafted rookie out of Michigan, played with the Cardinals in the preseason before being released September 1. He signed to the practice squad the next day. In the preseason, Demens totaled six tackles, .5 quarterback sacks and a pass defensed.
To fill Demens' spot on the practice squad, the Cardinals signed wide receiver Devon Wylie Wednesday. Wylie, a 2012 fourth-round pick out of Fresno State, spent his rookie season with the Kansas City Chiefs and was released September 1.
