As their season opener against the New York Jets on “Monday Night Football” approaches, the reigning NFC champions are close to finalizing a contract extension with All-Pro left tackle Trent Williams, according to his agency, Elite Loyalty Sports.

Williams, previously the league’s highest-paid offensive lineman and widely regarded as its best left tackle, had fallen to sixth in average annual salary ($23 million per year) this past year. He sat out of training camp to seek a new deal after tackles Tristan Wirfs, Penei Sewell and Christian Darrisaw surpassed him on the pay scale during the offseason. Wirfs of the Tampa Bay Buccaneers is currently the highest-paid blocker at $28.1 million per year after signing a five-year, $140.6 million extension.

The 49ers have been juggling competing priorities in recent weeks, but finally reached a contract extension with wideout Brandon Aiyuk on Thursday, ending his hold-in.
