The San Francisco 49ers and left tackle Trent Williams agreed to a two-year, $50 million extension, his agency unveiled Monday.
Elite Loyalty Sports unveiled that the contract includes $37 million fully guaranteed and a $22 million signing bonus. According to the agency, Williams is the first non-quarterback in NFL history to surpass $400 million in contracts and $225 million in guarantees.
He is now under contract through the 2028 season.
The 49ers had declined to exercise a $10 million option bonus that was due March 20 and had struggled to find common ground on a reworked contract this offseason. However, general manager John Lynch stated at the NFL’s annual meeting in Phoenix late last month that talks had “intensified” between the sides.
Williams was previously slated to enter the 2026 season with no guaranteed money or years left on his deal with a salary cap number of $38.84 million, including a base salary of $22.21 million.
While there had been speculation that the 49ers might move on from Williams, they never actively looked to do so, especially considering that they would have had to eat a $34.15 million dead money charge while realizing just $4.69 million in savings if they traded or released him before June 1.
Further complicating matters for San Francisco was the lack of a proven replacement on the roster. The Niners added swing tackle Vederian Lowe from the New England Patriots in free agency and retained unique rights free agent Austen Pleasants but with an eye toward depth rather than stepping in for Williams.

For his part, Williams told ESPN in February that he was expecting the team to do some maneuvering with his contract, probably in the form of a short extension that would provide him further guarantees and give the team additional 2026 cap relief. He also expressed optimism that such a deal would be struck.
Now, Williams and the Niners can move forward with an eye toward him finishing his career in the Bay Area. Williams will turn 38 on July 19 and has told ESPN repeatedly that he’d like to play until he’s 40. This contract opens the door to such a scenario for both parties while also allowing Williams to continue bolstering his Hall of Fame resumé.
Williams earned another Pro Bowl nod and second-team All-Pro honors in 2025, bringing his career totals to 12 Pro Bowls and five All-Pro teams. Under contract for three more years, Williams has a chance to tie Bruce Matthews’ record of 14 Pro Bowl selections by an offensive lineman while also continuing to chase his first Lombardi Trophy.
