LOS ANGELES, Feb 2, (AP): Luka Doncic led Dallas to the NBA Finals last season. Anthony Davis won a championship with the Los Angeles Lakers.

They're switching teams now - in an absolute blockbuster.

Doncic is being traded by the reigning Western Conference champions Mavericks to the Los Angeles Lakers for Davis, a person with knowledge of the agreement said early Sunday.

Doncic, Maxi Kleber, and Markieff Morris are headed to the Lakers, while Davis and Max Christie are going to Dallas, said the person who spoke to The Associated Press anonymously because neither team can announce the deal while it awaits league approval.

The Utah Jazz also are involved in the deal, said the source. ESPN, which first reported the trade, said Jalen Hood-Schifino and two draft picks will be headed to the Jazz. The Dallas Morning News also reported those details on the trade.

The trade news broke about an hour after the Lakers beat New York at Madison Square Garden. Davis was not with the Lakers for the game; he has been back in Los Angeles because of an abdominal injury that needed assessing.

Doncic has not played for Dallas since Christmas Day when he was sidelined with a strained left calf.

"I believe that defense wins championships,” Mavericks general manager Nico Harrison told ESPN. "I believe that getting an All-Defensive center and an All-NBA player with a defensive mindset gives us a better chance. We’re built to win now and in the future.”

The deal, at least for now, would pair Doncic with LeBron James as the new 1-2 punch in Los Angeles, while Davis would be forming a new star duo with Kyrie Irving in Dallas.

And there was immediate shock on social media when the news hit.
