The Broncos activated Lock (undisclosed) from the reserve/COVID-19 list Tuesday, Aric DiLalla of the team's official site reports.
Lock was placed on the list after the rest of the Broncos quarterback room was deemed to be high-risk close contacts of Jeff Driskel, who tested positive for COVID-19 last Thursday. All of Lock, Brett Rypien and practice-squad member Blake Bortles were ineligible to play this past Sunday against the Saints, leaving QB in the hands of practice-squad wide receiver Kendall Hinton. With Lock back in the building, he'll be under center for Denver's next game Sunday night at Kansas City.
