Parker and Tomlin share a high five

The Steelers are alone atop the AFC North with a 2-and-0 record.  Cincinnati, Cleveland and Baltimore trail the Steelers by a game at 1-and-1.  Cincinnati lost to Cleveland last weekend and Baltimore lost to the Bengals back in Week One.  The Browns lost to the Steelers in Week One.  The Steelers will now turn their attention to the San Francisco 49ers, who visit Heinz Field this coming Sunday.  Steelers head coach Mike Tomlin is expected to update the status of linebacker James Harrison when Tomlin meets with the media at Noon today for his weekly press conference.  Harrison was taken off the field at halftime last Sunday with a neck injury.  He did return to the sidelines but did not play in the second half.  The Steelers are eight-and-a-half point favorites.
