ENGLEWOOD, Colo. — With starting quarterback Drew Lock expected to miss three to five weeks with a shoulder injury, the Denver Broncos have agreed to terms with Blake Bortles on a one-year deal, a source told ESPN’s Jeremy Fowler on Tuesday.

Bortles will start the mandated COVID-19 protocols, which will include multiple tests spread over four days.

Coach Vic Fangio on Monday said that the Broncos had brought in a quarterback and that the player wouldn’t be able to attend meetings or practice “until Friday or Saturday.”

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.
