LeBron James Lets Go Of Jersey No. 23 Following 'Space Jam 2' Release -- Here's Why! LeBron James will show a massive change inside the court by not wearing his usual jersey no. 23 in the next season. Ahead of the release of his new movie "Space Jam: A New Legacy," LeBron decided to continue wearing the no. 6 jersey in the next season. According to The Athletic's Shams Charania and Tim Cato, the move will give a nod to the movie where he wears the jersey No. 6. In 2019, he almost changed the number as well when Anthony Davis joined the Lakers from the New Orleans Pelicans. At that time, LeBron wanted to give him the no. 23 as it remains the only number he has been wearing since college.
