They became the first father and son to play together in the NBA — and in the league at the same time — when they came off the bench with four minutes left in the first half against the Minnesota Timberwolves.
Broney, 20, who played alongside his father during the preseason, earned an offensive rebound in his debut, playing just over two and a half minutes with LeBron before returning to the bench.
Ken Griffey Sr. and Ken Griffey Jr., who accomplished the same baseball feat for the Seattle Mariners in 1990, were courtside to congratulate the history makers before the game.
LeBron, 39, also tied Vince Carter’s record as he appeared in his 22nd NBA season.
He scored 16 points while Anthony Davis contributed 36 and 16 rebounds in the Lakers’ 110-103 victory in coach JJ Reddick’s first game.
The win marked their first season-opening win since 2016.
LeBron told ESPN, “My family always comes first. I missed a lot of his stuff, so being able to experience that moment with my son was among the greatest gifts I’ve ever had.”
Broney described the moment he walked into the game with his dad as “a crazy moment I’ll never forget”.
Meanwhile, the defending champion Boston Celtics tied the NBA record for most three-pointers in a game when they opened their season with a 132-109 victory over the New York Knicks.
The Celtics tied the record of 29 held by the Milwaukee Bucks with nearly nine minutes remaining, but missed 13 attempts to set a new mark.
Jayson Tatum made eight 3-pointers among his 37 points.
