Steelers' Heath Miller, Ryan Shazier exit early in Seattle

The Pittsburgh Steelers lost a pair of starters in the first half against Seattle on Sunday.

Tight end Heath Miller exited with a rib injury after catching 5 passes for 45 yards in the first quarter. His return was initially called probable, but later downgraded to questionable despite returning to the field after a locker room evaluation. 

Linebacker Ryan Shazier suffered a concussion and was replaced in the lineup by Vince Williams and Sean Spence.
