Cardinals sign Dwight Freeney, place LB Kenny Demens on IR
Freeney's signing came after the Cardinals' top outside pass rusher, Alex Okafor, went down with a calf injury in Sunday's 42-17 victory at Detroit.
The 35-year-old Freeney, a seven-time Pro Bowl player and three-time first-team All Pro, ranks fifth among active players in career sacks with 111 1/2 and led the league with 16 sacks in 2004.
Demens, a significant contributor on special teams, tore an ACL in the Lions game.
