JACKSONVILLE, Fla. (AP) _ The Denver Broncos waived running back Quentin Griffin on Sunday and signed safety Curome Cox from the practice squad.

Griffin, the team's opening-day starter last season, was cut early last month but re-signed after injuries to Mike Anderson and Tatum Bell.

Cox spent the first four weeks of this season on the practice squad. He also was on Denver's practice squad for the final six games last season.
