James scored a season-high 52 points and had 11 assists Wednesday in the Cavaliers' 107-102 victory at New York. He was believed to have a triple-double when he grabbed what went down as a 10th rebound with less than 2 seconds left.
However, the league reviewed the game and ruled that a rebound given to James with 39.3 seconds remaining should have been credited to Wallace. The corrected statistics now have James with nine rebounds and Wallace with two.
"I don't go out there for the numbers, I just play my game," James said after Wednesday's game when he was still thought to have recorded a triple-double. "You guys seen every phase of my game tonight, the scoring, the rebounding, the assists and defensively just trying to attack the opposing team.
"I never thought you could look at the box score and see somebody with 50 with a triple-double, but it's happened."
James will get a chance to face off against Bryant when the Lakers visit Cleveland on Sunday.
A release from the league said: "All NBA games are reviewed to ensure the accuracy of the game statistics."
Had the triple-double stood, it would have been the first 50-point game in a triple-double since Kareem Abdul-Jabbar in 1975.
James now remains with three triple-doubles this season and 20 for his career.
