The Cardinals elevated Cooper from the practice squad Saturday ahead of Sunday's game versus the Chargers, Darren Urban of the team's official site reports.
The journeyman wide receiver finds himself on Arizona's active roster for the third time in his seventh pro season. It remains to be seen if Cooper will be active this weekend, which may depend on whether Greg Dortch (thumb) joins Rondale Moore (groin) on the sideline. If that comes to pass, Cooper and Andre Baccellia would be the candidates to get snaps behind wide receivers DeAndre Hopkins, Marquise Brown, A.J. Green and Robbie Anderson.
