Bowman, 29, has played all six seasons of his NFL career with the Chicago Bears. He played in 16 games last season, and 73 in his career.
He has 157 total tackles, 10 interceptions -- including three in 2013 -- and two forced fumbles and five fumble recoveries. Bowman is listed at 6-foot-1-inch and 193 lbs.
Bowman will be used as a backup corner and safety in some sub packages, but will figure more into the Giants' special teams plans. Another quality depth acquisition by Jerry Reese this offseason.
