The Cardinals signed O'Donnell to their active roster Friday.

EDGE Analysis

The 34-year-old's signing Friday likely suggests that Blake Gillikin (back), who popped up on Arizona's injury report Thursday as a limited practice participant, could miss the Week 6 matchup against the Colts. O'Donnell, a 10-year NFL veteran, is now expected to assume Arizona's top punter and holder duties if Gillikin is sidelined Sunday.
