ESPN’s Josina Anderson confirmed the news and reported Siliga’s deal is for one-year and worth up to $1.4 million with $250,000 guaranteed.
Siliga shared an Instagram post of himself signing his new contract shortly after the news broke:
The former undrafted free agent has spent the past three seasons with the New England Patriots and played in a career-high 13 games last year with 28 tackles.
He was on the field for 23.2 percent of the Patriots’ defensive snaps, per Football Outsiders, second-lowest among players with more than four snaps.
He also has ties to Seattle, having competed with the team for part of its 2013 training camp, according to Sheil Kapadia of ESPN.com.
Before adding Siliga, Seattle had also on Monday interviewed defensive linemen Brandon Thompson, per Jeremy Fowler of ESPN.com, and Sammie Lee Hill, per Ian Rapoport of NFL.com. Cam Thomas visited the team last Thursday, per Rapoport.
Siliga will head to Seattle as the Seahawks hope to maintain a run defense that last year held opponents to 83.4 yards per game, tops in the NFL.
The Seahawks have $11.1 million in cap space, per Over the Cap, and by signing a player of Siliga’s caliber, it appears they’re seeking a short-term option who won’t cost much.
