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

The NBA has fined the Dallas Mavericks $750,000, saying the team engaged in “conduct detrimental to the league” by sitting out most of its key players against the Chicago Bulls on April 7 despite still having a chance to reach the postseason.

Jason Kidd is coming back to Dallas again, this time to replace the coach he won a championship with as the point guard of the Mavericks 10 years ago.
