Los Angeles, California - LeBron James is reportedly considering retirement from basketball after the Los Angeles Lakers were swept out of the NBA playoffs by the Denver Nuggets on Monday.

ESPN reported that the 38-year-old was thinking about "walking away" from the sport after the Lakers' defeat brought the curtain down on his 20th season in the league.

Chris Haynes, a reporter for the TNT broadcaster, said in a separate tweet citing league sources that James's retirement was "under consideration."

James himself fueled speculation about his future in a cryptic post-game press conference, saying that he planned to take time to reflect on the next stage of his career after the Lakers' exit.

Asked for his thoughts on the past season, in which he became the league's all-time leading points scorer and took the Lakers to the brink of the NBA Finals, James said the campaign had been "challenging."

"I don't know. I think it was okay. I don't like to say it's a successful year because I don't play for anything besides winning championships at this point in my career," said James, who delivered a vintage 40-point performance in the Lakers' 113-111 loss on Monday.

"I don't get a kick out of making a Conference (finals) appearance. I've done it, a lot. And it's not fun to me to not be able to be a part of getting to the Finals."

"But we'll see. We'll see. We'll see what happens going forward. I don't know. I've got a lot to think about to be honest."

"Just for me personally, going forward with the game of basketball, I've got a lot to think about," he added.

James signed a two-year contract extension with the Lakers last August that would keep him at the club through the 2024-2025 season.

He has long said that he wants to extend his career so that he gets to share the NBA stage with his eldest son Bronny James, who will play college basketball next season at the University of Southern California, and who could conceivably enter the league in time for the 2024-2025 campaign.

However, in his postgame remarks on Monday, James hinted that the demands of the NBA's marathon 82-game season might be taking their toll.

"For me, it's all about availability for me and keeping my mind sharp and things of that nature, being present on the floor, being present in the locker room and bus rides and plane rides, things of that nature," James said.

"It's challenging."
