Trent Williams was traded to the San Francisco 49ers from the Washington Redskins in a big move at the start of day three of the NFL Draft.

Star left tackle Williams did not make an appearance in 2019 due to a dispute with the Redskins, who received a fifth-round pick in this season's draft and a third-round pick in 2021 from the Niners.

Beaten in the Super Bowl in February, San Francisco were in need of defensive reinforcements and reportedly saw off competition from the Minnesota Vikings and the Cleveland Browns to secure Williams' services.

The Vikings, according to reports, had been in line to commit to a similar deal as the Niners, but 31-year-old Williams – a seven-time Pro Bowler – preferred a move to San Francisco.

Williams leaves the Redskins after nine years with the team, having made 119 starts.

On Saturday, he posted on his Instagram account: "Can someone make me a San Fran edit."

San Francisco later confirmed the deal was complete, pending Williams passing physical tests.

Washington selected tackle Saahdiq Charles from LCU as Williams' replacement, with the 108th pick overall.
