The Denver Broncos made two more free agent signings today, adding to their growing group of tight ends and adding depth on the defensive line. The Broncos finalized a one-year deal with tight end Dante Rosario, who played with new head coach John Fox in Carolina in his first four pro seasons. Rosario enjoyed his best pro season last year, catching a career-high 32 passes. The Broncos also signed former Jacksonville Jaguars defensive end Derrick Harvey to a contract. Harvey was the eighth overall pick in the 2008 draft but quickly wore out his welcome in Jacksonville, recording just eight sacks in three seasons. Harvey projects as a backup at defensive end. The Broncos are still looking to add a defensive tackle, with veterans Ty Warren and Jamaal Anderson on their shopping list.
