(AP) — The Denver Broncos are left with a practice squad rookie receiver and a backup running back to take snaps against the New Orleans Saints on Sunday after losing all four of their quarterbacks to coronavirus concerns. No. 3 QB Jeff Driskel tested positive for COVID-19 on Thanksgiving and the league on Saturday determined that Drew Lock, Brett Rypien and Blake Bortles were deemed high-risk close contacts. A person familiar with the investigation told The Associated Press that the three quarterbacks weren’t wearing their masks the whole time they were around Driskel on Wednesday.
