Hagan appeared in all 16 games for New York last season, mostly on special teams. He caught eight passes for 101 yards, including a 23-yard touchdown Dec.21 against Washington. He was released in September.
The Giants also signed defensive tackle Dwayne Hendricks to their practice squad Tuesday. Hendricks was on the team's practice squad for the last 10 weeks of the 2009 season.
