LeBron James frustrated by back problem

LeBron James has admitted that he is still struggling with a long-term back problem.

The four-time MVP claims that he was close to full fitness before the victory over the Toronto Raptors on Friday night, but insists that he will not be missing any games soon.

"It's not where I was before the Toronto game," James told reporters after scoring 26 points in the Heat's win over the Charlotte Bobcats on Sunday.

"It's frustrating, but I'm still able to help our team. As long as I can do that, I'll be in uniform.

"I'm just trying to stay on it and do the same things I did when I got it back close to a 100%."

James boasts an average of 26.2 points per game this season.
