The Steelers could be without one or both of their top running backs when they open the regular season in two weeks against the visiting Cleveland Browns. Steelers coach Mike Tomlin reiterated Monday that Le'Veon Bell and LeGarrette Blount will be punished after getting arrested on marijuana possession charges Wednesday, shortly before the team flew to Philadelphia for a preseason game the following night. Tomlin said the Steelers have not ruled out suspending Bell, who was also charged with driving under the influence, and Blount. "Everything's on the table," Tomlin said. Steelers president Art Rooney II indicated Monday that the Steelers would move deliberately when considering discipline for the pair. "There are parts of this that are going to have to go through the legal process and the league review process," Rooney II told on Monday. "We'll just have to deal with it as that process unfolds." Bell and Blount are the only running backs on the Steelers' roster who have any NFL carries, and losing one or both of them would be a significant blow to an offense that wants to establish the run this season. The two players are also subject to NFL discipline, though a league suspension probably wouldn't be levied until next season.
