ENGLEWOOD, Colo. -- The Denver Broncos continue to work the trade market for their big-ticket additions this offseason.

The team made its second significant trade of the offseason Wednesday when it acquired five-time Pro Bowl defensive lineman Jurrell Casey from the Tennessee Titans, league sources confirmed to ESPN.

The Broncos, according to sources, will send a seventh-round pick (No. 237 overall) in next April's draft to the Titans for the 30-year-old Casey.

The deal comes 14 days after the Broncos acquired cornerback A.J. Bouye from the Jacksonville Jaguars for a fourth-round pick. With the two trades, the Broncos are scheduled to have 10 picks in the draft.

Casey has been a durable, productive and often dominant player in his nine seasons in the NFL, all with the Titans. He has started at least 14 games each season and has been selected to the Pro Bowl for the past five years.

Casey, as an interior pass-rusher, has also had at least five sacks in each of the past seven seasons.

He missed two games last season with a neck injury but returned to start the last six games of the regular season and all three of the Titans' playoff games. He had two sacks in the Titans' upset victory over league MVP Lamar Jackson and the Baltimore Ravens in the divisional round.

The Broncos have been pushing hard to sign an interior defensive lineman this offseason. They had negotiations with former Houston Texans defensive tackle D.J. Reader but left the bidding before Reader agreed to a four-year, $53 million contract with the Cincinnati Bengals.

The Broncos have three defensive linemen -- Shelby Harris, Derek Wolfe and Adam Gotsis -- who are unrestricted free agents, so Casey's arrival is important.

At the scouting combine last month, Broncos president of football operations/general manager John Elway said that all three of the team's free-agent defensive linemen would test the market and the Broncos would proceed with their plan at the position.

Casey's contract -- a four-year, $60.4 million extension he signed in 2017 -- is a hefty addition to the Broncos and likely at least one of the reasons Denver was able to secure such a productive player for a third-day draft pick.

Casey will count $11.788 million against the Broncos' cap this season and is scheduled to count $12.281 million in 2021 and $13.85 million in 2022. Also, $5.45 million of Casey's base salary this season is scheduled to become guaranteed on Sunday.

The trades for Casey and Bouye and the signings of guard Graham Glasgow and backup quarterback Jeff Driskel have been the bulk of the Broncos' work in the offseason. They did not tender an offer to cornerback De'Vante Bausby -- who finished last season on injured reserve with a neck injury and was scheduled to be a restricted free agent -- but agreed to a one-year deal with Bausby on Tuesday.
