DENVER - Short of linebackers for their special teams units, the Denver Broncos adjusted Saturday by promoting Quentin Gause from their practice squad.

To make room for Gause on their 53-man roster, the Broncos placed receiver Marlon Brown on season-ending injured reserve. Brown was signed by the Broncos three weeks ago after he was out for an extended period recovering from a back injury. He was not active in the Broncos’ previous two games.

The Broncos needed Gause because of the trickle up affect that started with the hamstring injury to starting inside linebacker Brandon Marshall.

Corey Nelson will not be as involved in special teams as he will start in Marshall’s place Sunday against Tennessee. Backup linebacker and special teamer Zaire Anderson may also get more defensive snaps Sunday.

The 6-0, 243-pound Gause is an undrafted rookie from Rutgers who spent time earlier this year with New England and Philadelphia before he was signed to the Broncos’ practice squad on Oct. 18.
