MIAMI -

Heat star LeBron James re-aggravated a back injury in the Heat's win Friday night over the Raptors.

LeBron was asked about it after the game and said, "Yeah, it bothered me, bothered me throughout the game.  I kind of reinjured my back a little bit.  So that's definitely a step backwards.  But, we'll see what happens in the next couple of days."

LeBron said the injury happened during the second quarter, "Got hit from behind and then (Tyler) Hasbrough got me pretty good too.  But it's all good, it's a good game." 

The Heat have won 9 straight games.

They host Charlotte on Sunday.

There's no word yet if LeBron's back will be ready to go.
