Broncos' Jarrett Guarantano: Will be available vs. Arizona

Denver elevated Guarantano from its practice squad to the active roster Saturday ahead of Sunday's game versus the Cardinals, Ben Swanson of the Broncos' official site reports.

Less than two weeks after signing with the team, Guarantano will be called on to serve as the backup quarterback with Russell Wilson (concussion) out. The rookie from Washington State has yet to play a regular-season NFL snap.
