Doughty can officially sign the new deal as of July 1. The superstar blue-liner is entering the final season of his current eight-year pact that carries a $7-million cap hit, per CapFriendly.
"Drew Doughty is one of the best defensemen in the world and we are obviously excited to have reached this point in the process in which he has committed to the Kings long-term," general manager Rob Blake said in a statement. "This is great news for our organization and our fans and we will comment further once the contract has been signed and formally announced."
The second overall pick in 2008, Doughty has been a mainstay with the Kings, guiding the franchise to its first Stanley Cup in 2012, and a second championship two years later. In 2015-16, he captured the Norris Trophy as the defenseman of the year.
In 770 career games, Doughty has tallied 102 goals and 320 assists.
