Falcons running back Steven Jackson, who missed Sunday's 27-23 loss to the Dolphins while nursing a hamstring injury, is still expected to be sidelined another two to three weeks, according to a league source. That means Jackson is set to miss Sunday night's showdown with the Patriots. Jackson sustained the setback -- originally called a thigh injury -- in the first quarter of a Week 2 win over his former team, the Rams. He exited that game immediately after scoring an eight-yard touchdown off a pass from Matt Ryan. Jackson said last week he was getting better but would not discuss his status in detail.
