The Los Angeles Lakers star will not play against the Denver Nuggets on Sunday due to an ankle injury.
Going forward, James is considered a day-to-day decision.
After more than six weeks out with a right midfoot injury, Anthony Davis will play his second game in a row on Friday.
Entering Sunday, James had missed three of the Lakers' past five games, a stretch in which Los Angeles has gone 0-5 to fall out of a play-in spot in the West.
James said he wasn't sure if he would play against the Nuggets due to his injury.
James hopes it reacts the right way when he wakes up in the morning.
The Lakers have five games left to play and trail the Spurs by a game. Los Angeles has to pick up two games on San Antonio before the end of the season to get the final play-in spot. The Lakers have a schedule that includes two games against Denver, one against Phoenix, one against Golden State and one against Oklahoma City.
