LeBron James has been ruled out of Sunday's game against the Chicago Bulls by Miami Heat head coach Erik Spoelstra.

The Heat forward suffered a broken nose in a clash with Serge Ibaka during the win over the Oklahoma City Thunder on Thursday night, and Spoelstra confirmed that he is not ready to return to the court ahead of Chicago's visit to the AmericanAirlines Arena.

"It's a little bit of everything - pain, headaches," James told reporters on Saturday. "Hopefully it'll get better the next couple of days, hopefully it gets better the next day.

"But if not, I'm not going to rush it. I feel better today than when it happened. I'm not bleeding."

James will now be hoping to be ready for the game against the New York Knicks on Thursday.
