Quinnen Williams signs $105.9 million extension with Dallas Cowboys

The Dallas Cowboys have signed defensive tackle Quinnen Williams to a three-year contract extension worth $105.9 million. The deal, which includes $101 million in guarantees, secures Williams through the 2030 season.

This extension serves as the final component of a major defensive overhaul initiated by the Cowboys. Last season, Dallas acquired Williams from the New York Jets in exchange for defensive tackle Mazi Smith, a 2027 first-round pick, and a 2026 second-round pick.

The acquisition of Williams follows a blockbuster trade in August 2025, in which the Cowboys sent edge rusher Micah Parsons to the Green Bay Packers for defensive tackle Kenny Clark and draft picks. By securing Williams alongside Clark, the Cowboys have established a new interior defensive line core.
