Doncic announced on social media that his foundation is donating $500,000 to help recovery efforts from the wildfires that ravaged L.A. last month.
"It's been so sad to see and learn more about the damage from the wildfires since I landed in LA," his post said. "I can't believe it and I feel for all the kids who lost their homes, schools and the places where they used to play with their friends.
"Today, my foundation is donating $500,000 to immediate recovery efforts. I am also committed to helping rebuild courts, playgrounds and fields that were destroyed, because every kid needs a safe place to play.
Doncic ended his message saying: "We're here to help, now and for the long haul."
The Lakers acquired Doncic in a trade that sent Anthony Davis to the Dallas Mavericks - a move that stunned the basketball world. He is expected to make his Lakers debut Monday.
