Cavaliers forward J.J. Hickson received X-Rays and an MRI this morning at Cleveland Clinic Sports Health after experiencing some recent low back soreness. The MRI revealed a stress reaction in his lower back. He is listed as Out and will now undergo a period of rest and treatment over the next two to three weeks. He will be re-evaluated after that and his status will be updated as appropriate.

Hickson hasn't been playing much lately, mostly due to mental breakdowns on defense.
