The Broncos signed Bortles to the practice squad Monday, Troy Renck of Denver 7 News reports.
Bortles was released by the Broncos on Saturday, but he'll stick around as a scout team quarterback. The Broncos will push forward with Drew Lock as their starting quarterback, Brett Rypien as the backup and Jeff Driskel as the No. 3 option. If any of the three get hurt, Bortles likely will get called up again.
