With the Patriots losing LeGarrette Blount to the Pittsburgh Steelers last week, there's a bit of a void to fill at the running back position behind Stevan Ridley and Shane Vereen. Perhaps the Patriots are close to filling it. NFL Network reports that former Bears running back Michael Bush is set to visit the Pats. Bush, a six-year NFL veteran, is coming off the quietest year of his career. After four seasons with the Raiders - including a 2011 season that saw him rush for 977 yards and seven touchdowns on 256 carries, and catch 37 passes for 418 yards and a touchdown - Bush signed with the Bears on a four-year, $14 million contract.
