Lebron James cast doubt on his future with the Los Angeles Lakers after their season-ending defeat by the Denver Nuggets.

The 38-year-old, the top scorer in NBA history, even sparked rumours of retirement following the 113-111 loss in game four of the Western Conference finals.

“We’ll see what happens going forward,” James said at his post-game press conference.

“I don’t know. 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.

“It was a very challenging season for me, for our club. It was a pretty cool ride, but I don’t know.

“I don’t get a kick out of making a Conference appearance. I’ve done it a lot and it’s not fun to me to not be a part of getting to the (NBA) finals.”

James scored 40 points against the Nuggets but missed two shots to tie the game in the dying seconds.

He has previously revealed a desire to play alongside his son Bronny, 18, who currently plays college basketball for the University of Southern California and will be eligible for the NBA next year.
