Tank Johnson was activated by the Dallas Cowboys on Monday, after completing an eight-game suspension and is set to play his first game with his new team. Coach Wade Phillips said Johnson had been added to the 53-man roster and would play Sunday for the NFC East-leading Cowboys (7-1) at the New York Giants. Johnson had been on the reserve-suspended list since Sept. 19, the day after he signed a two-year deal with Dallas. "He will be part of our rotation," Phillips said. "I think he'll help us."
