On Tuesday, the Broncos placed defensive tackle Ty Warren on injured reserve with a triceps injury and waived offensive lineman C.J. Davis.
The club filled those roster spots by re-signing quarterback Caleb Hanie and adding a veteran presence on the offensive line, signing center Dan Koppen.
The team also dropped offensive lineman Wayne Tribue from the practice squad.
Koppen — a 10th-year lineman — won two Super Bowls with the New England Patriots, where he spent the first nine years of his career.
The former fifth-round pick missed all but one game in 2011 after being placed on injured reserve. In his career, Koppen has started 120 of 121 games played, earning a Pro Bowl berth and second-team All-Pro honors in 2007.
Hanie was released last Saturday before the Broncos opened the season against Pittsburgh, in a move that Head Coach John Fox called “procedural,” in order to provide “some flexibility moving forward.”
The fifth-year quarterback completed 22 of his 39 passes during the preseason for 246 yards, a touchdown and an interception. He was originally signed as a free agent on March 25.
