Washington has agreed to terms to trade left tackle Trent Williams to the 49ers, according to NFL Network's Ian Rapoport, Tom Pelissero and Mike Garafolo.
San Francisco will send a fifth-round pick this year and a 2021 third-round draft pick to Washington in exchange for Williams, reports NFL Network.
ESPN previously reported that the 49ers had "expressed interest" in Williams, but would likely wait to see if Joe Staley plans to retire before taking action. San Francisco's deal indicates Staley's retirement is a strong possibility.
Washington and the Vikings reportedly had previously discussed a possible trade for Williams for months, but the NFL Network reported Friday night that deal was "off the table" when Minnesota selected Boise State offensive lineman Ezra Cleveland at No.
