Robinson has missed two exhibitions games and a team scrimmage with a torn hamstring. Atlanta (1-1) visits the Miami Dolphins (2-0) Friday night.
Robinson said after Monday's practice that he is still antsy. He says though it's been a long tme since he was "out here running around with the guys," he was happy the injury was "getting better."
Coach Mike Smith says Robinson's status against Miami will be a game-time decision.
The Falcons, whose starting defense struggled against New England's first-team offense last week, signed Robinson to a six-year contact with approximately $22.5 million guaranteed five months ago.
