Pittsburgh Steelers tight end Heath Miller will not return to Sunday's game against the Seattle Seahawks due to a rib injury.
Miller was initially ruled probable to return after he went to the locker room, but was quickly downgraded to questionable.
It isn't clear when Miller suffered the injury.
Jesse James and Matt Spaeth will see increased snaps in Miller's absence.
Miller had five catches for 45 yards before exiting the game.
