LeBron James is considering retirement after the Los Angeles Lakers were swept in the Western Conference Finals by the Denver Nuggets, sources told Chris Haynes of Bleacher Report.

James has "a lot to weigh," according to the source.

"I got a lot to think about. … just personally, with me moving forward with the game of basketball, I got a lot to think about," said James in his post-game press conference.

James is expected to take his time before making a decision on whether to return for his 21st season.

James currently has two years and $97 million left on his contract, which includes a player option.
