ENGLEWOOD, Colo. — After placing three defensive lineman on injured reserve within the last two weeks, the Broncos added reinforcements to the position group on Wednesday.

The Broncos signed veteran defensive lineman Timmy Jernigan, the team announced.

Denver also promoted running back LeVante Bellamy and outside linebacker Derrek Tuszka from the practice squad to the active roster.

In a corresponding roster move, the Broncos officially placed Elijah Wilkinson on injured reserve. Denver previously announced this week that Jurrell Casey and Austin Calitro had been placed on IR.

Jernigan, a seven-year veteran, spent the first three weeks of the season with the Jaguars. He played 27 percent of the team's defensive snaps but tallied just one tackle and one quarterback hit.

A former second-round pick by the Ravens in 2014, Jernigan spent the first three years of his career in Baltimore and then spent another three years in Philadelphia.

Jernigan has appeared in 74 career games and totaled 17.5 sacks, 133 tackles, 48 quarterback hits, 29 tackles for loss and a fumble recovery.

Jernigan joins Shelby Harris, Mike Purcell, Williams and McTelvin Agim as defensive linemen on the Broncos' active roster.

The Broncos placed DeMarcus Walker and Dre'Mont Jones on IR ahead of their Week 3 game against the Buccaneers. Denver promoted Williams to the active roster ahead of Week 3.

Bellamy and Tuszka will both be available if needed on Thursday, as well. Running back Phillip Lindsay is questionable for the game, while outside linebacker Jeremiah Attaochu has been ruled out.

Bellamy and Tuszka have twice been active for games this season after being elevated for game day. This promotion, though, means the players will remain on the active roster after game day rather than revert to the practice squad.

Denver is eligible to elevate two more players from the practice squad to their active roster for game day.

The Broncos' roster is again at the 53-man limit.
