According to Aaron Wilson of National Football Post, they've signed LeGarrette Blount:
Former New England Patriots veteran free agent running back LeGarrette Blount has agreed to a two-year contract with the Pittsburgh Steelers, according to league sources.
Blount visited the Steelers today.
He drew interest from several teams during free agency, including the Patriots and Baltimore Ravens.
The 6-foot, 250-pound Blount has a powerful running style.
Blount, 27, rushed for 772 yards and seven touchdowns last season for New England.
That included 189 yards and two touchdowns on 24 carries in the regular-season finale against the Buffalo Bills.
In a playoff victory over the Indianapolis Colts, Blount rushed for 166 yards and four touchdowns on 24 carries.
Blount will provide a nice backup to Bell while also providing insurance to the Steelers in the event Bell is injured again in 2014. He missed nearly the first full month of the 2013 season after suffering a foot injury during the preseason.
For his career, Blount had rushed for 2,711 yards and 20 touchdowns and has averaged 4.7 yards per carry for his career in four NFL seasons. As a rookie, he rushed for 1,007 yards and six touchdowns for the Tampa Bay Buccaneers.
