The Seattle Seahawks agreed to terms with linebacker O'Brien Schofield and cornerback A.J. Jefferson.

Schofield rejoins the Seahawks after recording seven tackles and one sack in 15 games as a reserve last season. He agreed to a two-year, $8 million deal with the New York Giants, but returned to free agency after the oft-injured pass rusher failed his physical.

In Seattle, he bolsters a pass rush that lost Chris Clemons this offseason and Schofield could play a far more significant role next season if he's able to stay healthy. He showed flashes during training camp, but then played limited snaps on a deep defense.

Jefferson provides needed depth at cornerback and is a player the Seahawks are familiar with. He was signed by the Arizona Cardinals as a rookie free agent in 2010 and spent two seasons with Arizona before being traded to the Minnesota Vikings on Sept. 1, 2012. He played in 25 games with seven starts over the past two seasons before being released last Nov. 25.

Jefferson will vie for a roster spot behind starters Richard Sherman and Byron Maxwell and reserve Jeremy Lane.

The Seahawks also announced they have declined the fifth-year contract option on guard James Carpenter. The 2011 first round pick has started 26 of 32 career regular-season games and started at left guard in Super Bowl XLVIII.
