The Packers opened up a roster spot for safety Abram, placing outside linebacker Rashan Gary on injured reserve having been ruled out for the season with an ACL tear.
Abram, 26, was taken 27th overall in the 2019 NFL Draft, but his professional career got off to a rough start when he tore his rotator cuff in his first regular season game, cutting his rookie season short after one half.
He played and started in 13 games in his second season, recording two interceptions and six pass breakups, before tallying a career-high 116 tackles as he started 14 games in his third season.
Abram's fifth-year option was declined by the Raiders, under a new regime with general manager Dave Ziegler and head coach Josh McDaniels.
With his release, Abram is now the fourth of the Raiders' six first-round draft picks under former general manager Mike Mayock to not make it through their rookie contract.
