ENGLEWOOD, Colo. — In the wake of injuries and COVID-19, the Broncos have added depth to their defensive line.

Denver signed defensive tackle Justin Hamilton off the Cowboys' practice squad, the team announced Tuesday.

The Broncos placed defensive lineman DeShawn Williams on injured reserve in a corresponding roster move. Williams suffered an elbow injury against the Raiders on Sunday that will sideline him for the final two games of the regular season.

Denver also signed defensive tackles Akeem Spence and Deyon Sizer and guard Tristen Hoge to their practice squad.

Hamilton, who entered the league in 2015 as an undrafted player, has appeared in 27 career games. He has spent the last two seasons with the Cowboys, for whom he's appeared in 19 games and made two starts. He has 20 tackles, one tackle for loss and three quarterback hits during his tenure in Dallas. Hamilton is a 6-foot-2, 315-pound player.

The addition of Hamilton should help along the defensive line, as Denver placed nose tackle Mike Purcell on the Reserve/COVID-19 list on Monday. The Broncos also placed defensive end Jonathan Harris on the Practice Squad/COVID-19 list. The two players' statuses for Sunday remain unclear.

Spence is a ninth-year player who was drafted in the fourth round of the 2013 NFL Draft. He has appeared in just one game this season but has recorded 205 tackles, 10.5 sacks, 19 tackles for loss and 35 quarterback hits across 110 career games.

Sizer, who has spent time over the previous years on the Broncos' practice squad, has appeared in one career game. Hoge played his collegiate ball at Notre Dame before transferring to BYU. He has spent time with the Jets and Browns after going undrafted in 2021, but he has yet to appear in a regular-season game.

The Broncos also protected TE Shaun Beyer, DE Marquiss Spencer and WR Seth Williams on their practice squad this week.
