Tennessee Titans tight end Delanie Walker will not play Sunday against the Denver Broncos because of a concussion.
Walker suffered the injury in last weekend's loss to the Indianapolis Colts.
The Titans figure to rotate Craig Stevens, Taylor Thompson and the recently acquired Visanthe Shiancoe at tight end against the Broncos.
Walker has 45 catches -- the second-highest total on the team -- for 454 yards and a team-leading five touchdowns this season.
