NBA star LeBron James ended speculation over his future on Wednesday, saying that he is not yet ready to retire and maintains his love for basketball.

James responded to his team, the Los Angeles Lakers, losing the Western Conference final to eventual champions Denver in May, by saying he had "a lot to think about" amid reports he was considering walking away from the sport.

But in a speech at the ESPY awards ceremony on Wednesday, James settled any fears he may be ready to quit.

"I don't care how many more points I score, or what I can or cannot do on the floor," James said after receiving the award for Best Record-Breaking Performance for passing Kareem Abdul-Jabbar as the league's all-time leading scorer.

"The real question for me is: Can I play without cheating this game? The day I can't give everything on the floor is the day I'll be done. Lucky for you guys, that day is not today," he said.

"In my 20 years playing this game and all the years before, I've never, ever cheated the game and I will never take it for granted," he added.

James, who will be 39 in December, dismissed suggestions that he wanted to continue playing in the NBA with one or both of his son's — his eldest son Bronny James, who will play college basketball next season at the University of Southern California, and could conceivably enter the NBA in time for the 2024-2025 campaign.

But he said that coaching his sons has helped to maintain his enthusiasm.

"You know what brings me back every year? It's watching and coaching my boys and their teammates," he said.

"I see those kids and it brings me right back to why I play. Those kids get me back to where I need to be, just the pure love of this beautiful game.

"So, yeah, I still got something left. A lot left," he added.

James explained his reflection after the loss to the Nuggets saying he had often had such questions for himself.
