LeBron James is suffering from lower back spasms and tweaked his back during a loose-ball scramble in the Miami Heat's win over the Los Angeles Clippers on Thursday.

"My back kind of locked up on me," he said. "The good thing is it's not my first time having back issues, so I'll be all right."

James scored 18 points and had six assists and five rebounds.

"Obviously he didn't look as spry as he normally does," Erik Spoelstra said. "But he was able to fight through it."
