The Broncos are “expected” to have interest in free agent defensive end Calais Campbell, according to KUSA-TV’s Mike Klis. That doesn’t guarantee a deal will get done, however, as Denver is running out of salary cap.

The Broncos could afford to sign Campbell, but they may not be able to afford both Campbell and quarterback Tony Romo. If one had to bet on which player was more likely to end up in Denver, Romo would be a safer bet.

Campbell (6-8, 280 pounds) went to high school in Colorado, so the idea of returning home might be appealing to him. But he’s going to be one of the best defensive ends available in free agency, so he may be too expensive for the Broncos.

A two-time Pro Bowl selection, Campbell owns 501 career tackles and 56.5 career sacks since entering the NFL with the Cardinals in 2008. Starting in all 16 games last season, Campbell totaled 53 tackles and eight sacks.

He also owns 42 career pass breakups and three career interceptions.
