LeBron James: 'I'm not 100%'

LeBron James has admitted that he does not feel 100% as his struggles with a back injury continue.

The four-time NBA MVP scored 25 points in the Miami Heat's loss to the Boston Celtics on Saturday night and he revealed to reporters after the game that he is not fully fit.

"I'm not 100%; my back is not where I want it to be," James said. "But I could still be effective.

"I thought I was tonight. I just didn't make enough plays to help us win."

James and the Heat will look to recover from their latest defeat when they face the Milwaukee Bucks on Tuesday evening.
