The Dallas Cowboys signed Sturgeon Bay’s Chris Greisen to their active roster Saturday. This is the second time that the 35-year old Greisen has appeared on an active roster. He spent three years (1999-2001) with the Arizona Cardinals. Greisen appeared in five games, completing 7 of 16 passes for 69 yards and one touchdown. Greisen will wear number 14 and serve as the Cowboys third quarterback behind Tony Romo and Stephen McGee. Greisen was not active for Sunday night’s game against the Giants at New York.
