Scott, 32, was placed on the reserve/injured list. The news came just hours after coach Bill Belichick continued to describe Scott's injury as day-to-day.
Last season, Scott played in 14 regular season games with nine starts. He made 44 tackles and had two interceptions. He signed with the Patriots before the 2005 season, which was cut short by a shoulder injury that October.
Meanwhile, Samuel continues holding out for a multiyear agreement after rejecting a one-year, $7.79 million contract.
