The Seahawks have acquired Sealver Siliga for the second time in three years, signing the free agent defensive tackle to a one-year deal Monday.
Siliga first came to Seattle in 2013 in a trade that sent guard John Moffitt to Denver, and spent time that season on the Seahawks' practice squad before signing with New England later in the season, taking over a starting role late in the year.
In three seasons with New England, the University of Utah product started 13 of 26 regular-season appearances, totaling 83 tackles (37 solo) and 5.5 sacks. Siliga, 25, also made five postseason starts with New England, including the Patriots' Super Bowl XLIX victory over Seattle, totaling 21 tackles in seven games.
