Schofield was signed by the Falcons on Wednesday, ESPN's Adam Caplan reports.
Schofield appeared in all 16 games for the Falcons in 2015, recording 30 tackles (24 solo), two sacks and a forced fumble. The former fourth-round pick will likely provide depth at the outside linebacker and defensive end positions without much IDP relevance.
Schofield recorded 30 tackles and two sacks in his first season with the Falcons.
Although it was his first year with the team, it wasn't his first under the tutelage of Dan Quinn, as the pair came over from Seattle in the offseason. Schofield only played in 47.6 percent of defensive snaps, so there's room for improvement if he can get on the field more often in 2016.
Seahawks offensive stars Marshawn Lynch and Doug Baldwin are active Week 10 against the Giants.
Both players came into the game listed as probable. Lynch is dealing with a calf injury. Baldwin has a groin issue. The team will also have Michael Bennett, Jordan Hill, Russell Okung, O'Brien Schofield and Max Unger. All five players were also listed as probable coming into the contest.
Marcus Burley and Byron Maxwell should play as well. They were both listed as questionable. Burley is dealing with a hamstring injury, Maxwell has a calf issue.
Guard Stephen Schilling is the only doubtful player who is active for the game.
The Seahawks have ruled out Zach Miller (ankle) and Bobby Wagner (toe) for Week 10 against the Giants. James Carpenter (ankle), Stephen Schilling (knee), Kam Chancellor (groin) and Malcolm Smith (groin) all missed practice Friday and were deemed doubtful for Sunday.
Marcus Burley (hamstring) was a limited participant in practice, while Byron Maxwell (calf) was a full participant Friday. Both were deemed questionable.
The following players were labeled probable: Russell Okung (calf), Doug Baldwin (groin), Max Unger (rest), O'Brien Schofield (head), Michael Bennett (toe), Marshawn Lynch (calf) and Jordan Hill (ankle).
The Seahawks re-signed linebacker O'Brien Schofield, who signed with the Giants in March only to have the deal collapse. The deal was voided after a knee injury surfaced during Schofield's physical.
Schofield played in 15 games last season for the Super Bowl champs, starting twice.
Free agent linebacker O'Brien Schofield's deal with the Giants is "dead," as reported by NFL.com Thursday. Schofield's two-year, $8 million deal with the Giants fell through after a knee injury surfaced during his physical, so his next step is not yet known.

In addition to signing defensive end John Abraham and offensive tackle Eric Winston on Thursday, the Cardinals released linebacker O'Brien Schofield and placed rookie receiver Ryan Swope on the reserve/Retired list. Linebacker Kenny Rowe was also signed.
Schofield's post-college career has been littered with bad luck: He tore his ACL during a 2010 Senior Bowl practice, then came back strong in 2011 with 4.5 sacks. He had 4.0 sacks last year before ankle surgery forced him to injured reserve.
Swope has dealt with concussion symptoms that go back to his college days since being drafted by the Cardinals in the sixth round of the 2013 NFL Draft.
