ENGLEWOOD, Colo. — The Broncos made a slew of roster moves on Tuesday, including promoting guard Austin Schlottmann to the active roster and placing guard Graham Glasgow on injured reserve.

Schlottmann, who spent the earlier portion of the season on the Broncos' practice squad, has appeared in three games this year and has played 35 games for the Broncos since the start of 2019. He played his first offensive snaps of the season on Sunday against the Cowboys.

Glasgow suffered an ankle injury of the final snap of the first half in Dallas, and he announced Monday that he would miss the remainder of the season.

The Broncos also waived cornerback Duke Dawson Jr. and placed cornerback Michael Ojemudia and linebacker Justin Strnad on the Reserve/COVID-19 list. Guard Netane Muti was activated from the Reserve/COVID-19 list with a roster exemption. He currently does not count against the 53-man roster.

Denver activated Dawson from the Reserve/Physically Unable to Perform list on Monday. He has not played in a game this season after tearing his ACL last season.

On the team's 16-player practice squad, the team signed linebacker Avery Williamson and tackle Casey Tucker and released wide receiver David Moore and tight end Caleb Wilson. The Broncos protected tackle Quinn Bailey, defensive lineman Jonathan Harris, linebacker Curtis Robinson and wide receiver Seth Williams on the practice squad this week.

Williamson briefly spent time on the Broncos' practice squad earlier this season. He is an eighth-year player with 85 career starts, and he appeared in a pair of games for the Titans as a special teams contributor.

Tucker, who entered the league as an undrafted player from Arizona State in 2019, has spent time on the practice squad for Detroit and Philadelphia. He has not appeared in a regular-season game.
