LeBron says back has been sore for couple weeks

LeBron James has been dealing with lower back soreness for a couple of weeks, which explains why the NBA's four-time MVP has said multiple times in the early going of this season that he's working his way to 100 percent.

"I've had a history of it, but I always keep a good eye on it so I should be all right," James said. "It ain't a great feeling, I'll tell you that — especially at nighttime when you're trying to sleep."
