The Denver Broncos have agreed to sign Blake Bortles to a one-year deal.

The Broncos will be without Drew Lock for three to five weeks with a shoulder injury.

Jeff Driskel will start Sunday's home game against the Tampa Bay Buccaneers, and Brett Rypien is expected to serve as backup after moving from the practice squad to the roster.

Borles was backup quarterback for the Los Angeles Rams last season.
