Original Text

The Carolina Panthers were already struggling to get the running game going against the Pittsburgh Steelers Sunday night, and a knee injury to Jonathan Stewart isn't going to help.

According to the Charlotte Observer's Jonathan Jones and Joe Person, Stewart left the game in the third quarter and is questionable to return:

Stewart has been ineffective carrying the ball this season, but Carolina's running back depth was already thin, with DeAngelo Williams (hamstring) and Fozzy Whittaker (quad) both inactive. If Stewart isn't able to return, bruising fullback Mike Tolbert will likely see most of the snaps out of the backfield, while undrafted rookie Darrin Reaves rounds out the rest of the available backs.

Ron Rivera will likely continue to turn to Cam Newton and the passing game as a result, giving the Panthers a mostly one-dimensional offensive attack in the meantime.
