With rookie defensive lineman Zach Allen dealing with a stinger injury, the Cardinals went with another Zach to help on the defensive line.
The Cardinals signed veteran Zach Kerr Wednesday to fill the void. The team already had an open roster spot after releasing both D.J. Swearinger and Miles Brown this week, having signed only wide receiver Pharoh Cooper in the meantime.
Coach Kliff Kingsbury said Allen would be limited in practice Wednesday and his availability for Sunday's game is undecided.
Kerr doesn’t necessarily increase the depth after the Cards cut Brown, an undrafted rookie defensive lineman. But he has experience, totaling 7½ sacks since coming into the NFL himself undrafted in 2014.
Kerr played for Cardinals defensive coordinator Vance Joseph the past two years in Denver. He actually had signed a contract extension in March with the Broncos, only to be cut at the end of August.
Veteran Jonathan Bullard had moved into the starting lineup last weekend against the Seahawks in place of Allen, prior to Allen’s injury. Corey Peters and Rodney Gunter remain the other starters in the 3-4 base alignment.
