LeBron James ruled out for two weeks

Cleveland Cavaliers forward LeBron James has been told that he will miss up to two weeks with back and knee injuries.

The four-time MVP has been forced to watch his side's last two games, and scans have revealed that David Blatt could be without the 30-year-old for the next seven games as the Cavaliers look to improve their standing in the Eastern Conference.

"First and foremost, we want to make sure LeBron is well and completely recovered," Blatt told reporters.

"The season is long and our main objective is that he will be well and strong for the rest of the season. But we have to fight it out and work every day to build others until he gets back after the time he needs."

Cleveland, who have lost their last three games, take on the Charlotte Bobcats on Friday night.
