The Giants have agreed to a three-year, $39 million deal with cornerback Adoree Jackson, according to ESPN's Adam Schefter.
Jackson, 25, was selected by the Titans with the No. 18 pick in the 2017 NFL draft. He's tallied two interceptions and 33 passes defended in 41 career starts.
Monday's signing marks New York's third major move of free agency. The Giants retained defensive lineman Leonard Williams on a three-year, $63 million deal on March 16, and they added wide receiver Kenny Golladay on a four-year, $72 million deal four days later.
