ENGLEWOOD, Colo. — The Broncos have added four players to their roster for Sunday's game against the Panthers, the team announced Saturday.

Denver promoted tight end Troy Fumagalli and safety Alijah Holder from the practice squad to 53-man roster, activated outside linebacker Derrek Tuszka from injured reserve and elevated linebacker Josh Watson from the practice squad as a COVID-19 Replacement.

Denver also signed cornerback Nate Hairston off Baltimore's practice squad, but he will not be eligible to play this weekend in Carolina. The Broncos will receive a roster exemption for Hairston as he goes through the league's COVID-testing protocols. Denver will need to make another roster move to adhere to the 53-man roster limit once Hairston officially joins the roster.

Hairston is a fourth-year player from Temple who has appeared in 40 regular season games for the Colts and Jets. He has recorded 95 tackles, two sacks, two interceptions and nine passes defensed in his career.

Fumagalli and Holder had each been elevated from the practice squad to game-day roster four times this season. Watson will be elevated for a team-high seventh time and will revert to the practice squad after Sunday's game without being exposed to waivers.

Tuszka returned to practice this week after suffering a hamstring injury earlier this season. The seventh-round pick has appeared in five games this year for the Broncos.
