PHILADELPHIA — Bronny James got the surprise call to play in the first quarter for the Lakers and finished with the first serious playing time of his NBA career.

It wasn’t great.

Bronny took off on a fast break and his shot was rejected by Adam Bona.

He got torched by 76ers guard Tyrese Maxey any time they were matched up.

His box score, well, it wasn’t any better: Bronny was scoreless for the Lakers in their 118-104 loss to the 76ers on Tuesday night. He missed three 3-pointers, all five shots overall and had three turnovers.

Bronny played 15 minutes just four days after he dropped a career-high 31 points for the South Bay Lakers of the G League.

“Maybe put him in a tough spot, flying out yesterday, nationally televised game and all that stuff,” Lakers coach JJ Redick said. “He didn’t play well. But he’s been playing great in the stay-ready games and he’s been playing great in the G.”

Dad knows Bronny still has plenty to learn in the NBA.

“He was able to get behind the defense on one and find Jaxson (Hayes) for a dunk. That was good,” LeBron James said. “Obviously missed his shots. It’s just about him just getting more and more comfortable. It’s his first extensive minutes with us. ... He’s going to continue to use that to get better and better.”

LeBron and Bronny made NBA history on Oct. 22 when they became the first father and son to play together during the Lakers’ season-opening win over the Timberwolves. Bronny then scored his first NBA basket for the Lakers in Cleveland on Oct. 30 at the arena where he watched his father as a child.

Bronny hadn’t played more than 6 minutes in any of his first 12 games and had scored four points all season.

“Just bringing energy. My coaches are telling me to come in and play smart, play my game and play for my teammates,” he said. “Just trying to do the right thing as a rookie.”

LeBron and the Lakers have already said Bronny will spend ample time this season with their G League affiliate as he works on his game.

“Just reps is the biggest thing for me,” Bronny said.
