MIAMI -- The Miami Dolphins have agreed to terms to trade starting left guard Ereck Flowers to the Washington Football Team in a deal that includes a swap of late-round NFL draft picks, sources confirmed to ESPN.

It's a return to Washington for Flowers, who revived his career there in 2019 when he moved from offensive tackle to guard. He then signed a three-year, $30 million contract with Miami last offseason.

The Dolphins will save $8 million in cap space and $9 million in guaranteed salary by sending Flowers to Washington. He had an up-and-down first season.

The Dolphins are entertaining the idea of moving 2020 second-round pick Robert Hunt from starting right tackle to guard and signing a right tackle in free agency, sources told ESPN's Jeremy Fowler. Solomon Kindley, the Dolphins' 2020 fourth-round pick, received significant playing time as a rookie and returns as a capable starting guard option along with recent free-agent signing D.J. Fluker.

Playmaker should still be a top priority for the Dolphins' first pick (No. 6 overall), but the Flowers deal raises the possibility that Miami uses one or more of its four top-50 picks in this year's draft on the offensive line.

The Dolphins are now set to move on from four of their top 2020 free-agent signings -- linebackers Kyle Van Noy and Shaq Lawson, Flowers and running back Jordan Howard -- in one season or less. It's a sign of the dangers of free agency, though good contract setups prevent significant dead cap on their books.

Flowers, 27, should fill Washington's need for another starting-caliber guard, and he returns to an offensive line he had success with in 2019.
