PITTSBURGH (AP) _ Steelers safety Troy Polamalu did not practice
all week because of a left knee injury and will not play Sunday in
Kansas City. He may miss the Nov. 29 game at Baltimore as well.
Polamalu sat out the Steelers' second through fifth games with a
ligament tear, only to injure the same knee during an 18-12 loss to
Cincinnati on Sunday.
Polamalu's latest injury is to a different ligament. He wore a
heavy brace as he watched practice this week.
Defensive end Travis Kirschke will sit out his third consecutive
game with a torn left calf muscle. He had been filling in for Aaron
Smith, who is out for the season with a torn right rotator cuff.
Nick Eason will start again at left defensive end. Tyrone Carter
will start at safety.
