LeBron James sat out the Cleveland Cavaliers' loss at the Oklahoma City Thunder on Thursday with a knee injury. James had played in every game for the Cavaliers in the regular season.

The soreness is located in the back of James' left knee and that he first started feeling the discomfort after the Cavs' win over the Toronto Raptors on Tuesday.

"Nothing major," David Blatt said. "Again, not a serious problem. We'll monitor it, we'll treat him and we'll see how he's feeling (Friday)."

James missed the Cavs' morning shootaround in order to receive treatment on "general soreness" in his left knee.

Blatt also said the knee hasn't been a lingering issue this season for James.
