Besides activating linebackers James Harrison and Jason Worilds from the Active PUP list on Tuesday, the Pittsburgh Steelers also waived running back Jason Ford, who was signed just prior to the second preseason game against the Indianapolis Colts. Ford carried 8 times for 42 yards in that game, but also apparently suffered a hamstring injury that forced him to be unable to play this past Saturday against the Buffalo Bills.
With wide receiver Mike Wallace signing his tender on Tuesday, the Steelers had to make a corresponding move, so Ford was more than likely waived injured with some sort of injury settlement.
The Steelers claimed running back DuJuan Harris off waivers from the Jacksonville Jaguars on Monday and he figures to get some late carries Thursday night in the preseason finale against the Carolina Panthers.
