According to Burt Lauten of the Steelers' public relations department, Bell suffered a foot injury and will not return to the game. The severity of Bell's injury is not yet known.
Bell has been dealing with a knee injury and missed Pittsburgh's first preseason game. He has been impressive during training camp practices but hasn't had a chance to separate himself from Isaac Redman and Jonathan Dwyer in the Steelers backfield in preseason play.
Bell carried the ball 382 times as a senior at Michigan State and had over 600 rushing attempts during his college career.
The Steelers usually bring rookies along slowly, but Bell has been given a chance to compete for the featured role in the backfield. Of course, he can only do that if he stays on the field.
