Schofield was claimed by the Seahawks off waivers from the Arizona Cardinals last July. He played in 15 games for Seattle and made two starts for the team early in the year while DE Chris Clemons was recovering from injury and LB Bruce Irvin was suspended.
He recorded seven tackles on the year and one sack last season.
Schofield agreed to a two-year, $8 million deal with the New York Giants this offseason. However, the deal was voided by the Giants after concerns over Schofield's knee during his physical with the team.
Schofield had a visit with the Tennessee Titans before electing to return to Seattle.
"Hey 12th man, I'm coming back home one more year. #blessed #backtowork #seahawks #12thMan" Schofield said on his Twitter account.
Jefferson spent the last two seasons with the Minnesota Vikings before being released by the team in November following an arrest on a domestic assault charge.
Jefferson was suspended by the league for four games at the end of last season that he was able to serve while a free agent. Jefferson reached a plea agreement in March. He received one year of probation in exchange for pleading guilty to a misdemeanor charge.
Jefferson appeared in 10 games last season for the Vikings and recorded five tackles and an interception.
Seahawks decline fifth-year option on G James Carpenter:
The Seahawks also announced Friday they will not pick up the fifth-year option on G James Carpenter's rookie contract.
The Seahawks had until Saturday to make a decision on Carpenter's option year. If Seattle had elected to pick up the option, Carpenter would have been scheduled to make $7.438 million in 2015. The contract would have been guaranteed for injury only.
With a long history of injuries and inconsistent play, it isn't surprising that the team wasn't winning to pick up Carpenter's option year.
Carpenter will now become an unrestricted free agent after next season.
Deadline passes for WR Doug Baldwin to sign offer sheet:
As a restricted free agent, WR Doug Baldwin had until 1 p.m. PT Friday to sign an offer sheet with another team. That did not happen.
Baldwin was given a second round restricted free agent by the Seahawks earlier this offseason. The tender gave Seattle a right of first refusal on any contract offered to Baldwin this offseason. It also would have entitled the Seahawks to a second round draft pick in compensation should Baldwin has signed with another team.
However, with no offer sheet executed on Baldwin, he will remain with the Seahawks this season.
Baldwin still has not signed his restricted free agent tender, which would pay him $2.187 million for next season. Baldwin can still sign the tender or negotiate a different contract with the team.
