Ben Roethlisberger placed himself in the concussion protocol toward the end of the Pittsburgh Steelers' loss at the Seattle Seahawks.

It has not yet been determined if Roethlisberger actually suffered a concussion.

Landry Jones finished the game at quarterback for the Steelers.

Ben Roethlisberger is expected to miss a few weeks with a mid-foot sprain.

The Steelers initially suspected Roethlisberger had a LisFranc injury to his left foot.

Roethlisberger suffered the injury on a sack by Aldon Smith.

"Ben is our franchise quarterback," Antonio Brown said. "We live and die with him. ... Hopefully he can be with us."

Le'Veon Bell is expected to miss the rest of the season with a badly torn MCL.

Bell missed the first two games of this season due to a suspension and their playoff loss last January with a knee injury.

Bell finished second in the league in yards from scrimmage last season, in part because of his incredible ability as a receiver. 

DeAngelo Williams will replace Bell as the starter for the Pittsburgh Steelers.
