Jackson, 25, is a former fifth-round pick of the Ravens back in 2012. He spent the first three years of his career in Baltimore before he was waived as the team cut their roster down to 53 players this past weekend.
In 2014, Jackson appeared in seven games and recorded 28 tackels and three pass defenses for the Ravens.
The Texans somewhat surprisingly cut Nix loose this past weekend just a year after taking him in the third-round of the 2014 draft.
However, the Giants wound up claiming him off of waivers along with CB Asa Jackson.
Nix, 24, is entering the second year of his four-year, $2,852,252 rookie contract that included a $575,252 signing bonus. He was set to make base salaries of $530,000 (2015), $620,000 (2016), and $710,000 (2018) over the remainder of the contract.
Nix didn’t appear in a single game during the entire 2014 season for the Texans.
