The Denver Broncos on Saturday signed quarterback Darrell Hackney to their active roster from their practice squad, Head Coach Mike Shanahan announced.

The Broncos also on Saturday waived tackle Matt Murphy, whom they signed on Monday.

Hackney (6-foot-0, 248 pounds) is a second-year player who spent the first eight weeks of the 2008 season on Denver's practice squad. He was on the Broncos' active roster for their final eight games of the 2007 campaign after beginning that season on their practice squad but has yet to appear in an NFL regular-season game.

In four games (1 start) with the Broncos during the 2008 preseason, Hackney completed 24-of-38 (63.2%) passes for 285 yards with one touchdown and no interceptions for a 94.7 passer rating.

A first-team All-Conference USA selection as a senior at the University of Alabama-Birmingham, Hackney entered the NFL with Cleveland as a college free agent on May 5, 2006.

He attended Douglass High School in Atlanta and was born on Aug. 7, 1983.
