Le'Veon Bell exits with foot injury
Bell carried the ball on all four plays on Pittsburgh's first possession, gaining a total of 9 yards, but he was replaced by Jonathan Dwyer during the team's second drive.
After the game, coach Mike Tomlin said Bell suffered a "mid-foot" injury and will get an MRI on Tuesday.
The second-round draft pick from Michigan State missed some practice time last week and was held out of Pittsburgh's preseason opener on Aug. 11 because of a sore left knee.
