The Seattle Seahawks have agreed to terms with defensive tackle Leonard Williams on a three-year, $90 million contract extension that keeps one of the NFL’s most productive interior linemen in the Pacific Northwest through the 2029 season, NFL Network’s Ian Rapoport reported Thursday.
The deal averages $30 million per year and includes $56 million in guarantees, according to ESPN’s Adam Schefter.
It is a substantial raise from the three-year, $64.5 million contract Williams signed in March 2024 after Seattle acquired him from the New York Giants at the 2023 trade deadline. That pact carried a $21.5 million average annual value. If Williams plays out the new agreement, Rapoport noted, his career earnings will reach $250 million.
Williams, 32, is a three-time Pro Bowler who earned second-team All-Pro honors in 2025. In his two full seasons with Seattle he has been a two-way anchor in Mike Macdonald’s defense: consistent sack production, elite double-team rates, and availability that has rarely wavered. He added postseason impact during the run that ended with a Super Bowl LX championship.
The timing follows Seattle’s long-standing policy of waiting until a player is in the final year of his deal before negotiating an extension. Williams was eligible this offseason. His 2026 cap charge sat near $29.6 million after a 2025 restructure that converted salary into bonus money and added void years. A new contract gives general manager John Schneider a chance to spread future charges and lock in a veteran who still occupies the middle of the defensive line at a high level.
Seattle has spent the last 18 months securing core pieces around the Super Bowl roster. Jaxon Smith-Njigba, Charles Cross, Abraham Lucas, Derick Hall, and cornerback Devon Witherspoon (extended earlier this month) are already under long-term deals. Williams was the next obvious name on that list. Byron Murphy II remains a year away from his own extension window.
Full year-by-year breakdown and signing-bonus details have not yet been released. Typical structures at this price point include a sizable bonus to create immediate cap relief and a heavy guarantee in the first two years.
Williams has said throughout camp that he tries not to let contract talk affect preparation. That approach has defined a 12-year career that began as the No. 6 overall pick by the Jets in 2015, continued with the Giants, and peaked in Seattle. The Seahawks just bet that the same durability and two-way impact continue for three more seasons.
The 12s keep No. 99.
