The San Francisco 49ers have acquired Trent Williams from Washington for a 2020 fifth round pick and a 2021 third round pick.

The 49ers moved to trade for Williams after Joe Staley decided to retire. The 49ers entered draft week hoping Staley would return.

Neither the 49ers or Williams are in a rush to sign an extension.

"I think the plan was to land him right now and then let the rest kind of work itself out," general manager John Lynch said. "I think it's always an advantage when you get someone in the building, on your roster. Now you've got a chance. We'll get a really good look at him. We'll see where the rest of our team is at, but right now we are just ecstatic that we were able to pull it off at a really opportune time.

"You're losing a great player like Joe at a very critical position, to be able to have everything line up that he was available right then and for us to be able to land him, I think very fortuitous for us, and we're very excited about that."
