ENGLEWOOD, Colo. — The Broncos have added depth at the cornerback position.

Denver activated cornerback Duke Dawson Jr. from the Reserve/Physically Unable to Perform list to the 53-man roster, the team announced Monday.

The Broncos also officially placed quarterback Drew Lock on the Reserve/COVID-19 list.

Dawson, a second-round pick in 2018 by the Patriots, has appeared in 26 games for the Broncos since the team traded for him ahead of the 2019 season. He has started four of those contests and recorded two passes defensed, one fumble recovery and 27 tackles.

The Florida product tore his ACL against the Carolina Panthers last December and has not appeared in a game in 2021. The team designated him to return to practice last week and had 21 days to activate him from the Reserve/PUP list.

Dawson could provide depth with Bryce Callahan on injured reserve and Pat Surtain II's status still uncertain.

Lock was not active for Sunday's game against the Cowboys due to COVID-19 protocols. Head Coach Vic Fangio said Monday that Lock had "somebody in his circle that he's close with" test positive for the virus. Lock has since returned to Denver.

Brett Rypien served as the team's backup quarterback against Dallas.
