Davis has worn No. 23 for seven years as a member of the New Orleans Pelicans.
Later Thursday night, James appeared to confirm in a tweet that he would be switching back to No. 6, which he previously wore with Team USA in the Olympics, and then with the Miami Heat.

James wore No. 23 during both of his stints with the Cleveland Cavaliers and last year in Los Angeles. A source close to James had earlier told ESPN's Dave McMenamin that a return to No. 6 was planned. Yahoo Sports was first to report the move.
Pictures from the set of "Space Jam 2" have shown James, who is starring in the sequel, wearing a No. 6 jersey.
Lance Stephenson wore No. 6 for the Lakers last season, but he is set to become a free agent this summer.
The trade for Davis, which now includes the Washington Wizards, will be official on July 6.
