The San Francisco 49ers are finalizing a contract extension for star left tackle Trent Williams, ending his holdout that kept him out of training camp and accruing over $4 million in fines. Williams' agency confirmed he is back in the Bay Area to finalize the deal ahead of the team's season opener against the New York Jets on Monday Night Football. He was previously on the reserve/did-not-report list and was owed a base salary of $20.05 million this season under his original six-year deal. The new agreement is expected to include guaranteed money, which was absent from his previous contract, making him one of the top-paid offensive linemen in the league. His holdout follows a recent contract extension for teammate Brandon Aiyuk, suggesting the 49ers are prioritizing securing their key players. Williams, a dominant force in the league, aims to maintain his elite performance as he enters his 14th NFL season.
