WATCH: LeBron James calls out fan who threw trash at son, Bronny, 'disrespectful'

LeBron James and the lakers fell 139-107 versus the Celtics in Boston on Monday, but LBJ is making headlines responding postgame to something that happened on a different basketball court.

James’ teenaged son, Bronny, was playing in a game of his own on MLK Day when someone threw something at the younger James’ back while he was inbounding the ball.

“I mean it’s just disrespectful, and it was a little kid I don’t know how old that little kid was,” LeBron said. “I don’t know if he learned that on his own or he learned that at home or whatever the case may be, but it’s disrespectful. I wonder how old that kid is if he was around Bronny’s age or Bryce’s age.”

James explained that he was at his son’s game and saw the official stop the game, but that he did not realize why that happened until he saw the video after arriving at TD Garden for his own game.

Bronny’s teammate, Zaire Williams, told reporters after the HoopHall Classic, which wrapped up in Springfield, Massachusetts Monday, “You’d be surprised by all the stuff Bronny has to go through. It’s not fair, but he doesn’t let it phase him at all. I’m learning how to be more like that from him and he’s younger than me.”

LeBron agreed that his 14-year-old is level headed, saying he’s calmer than both of his parents, adding, “I guess he’s taken that from me too. I let a lot of (expletive) go. (…) But that (expletive) made me mad when I saw it.”

The 90-minute ride in a vehicle (which USA Today Sports confirmed as the means of transportation) to Springfield from Boston is something James said he doesn’t mind, calling it “special,” that he and his son have games that close to one another so far from their California home.

“The only bad thing about today is I took two Ls,” LeBron said. “The James gang took two Ls today. There’s always better days.”
