Oklahoma City Thunder guard James Harden has been officially diagnosed with a concussion, and his timetable for return is unknown, according to the Oklahoman.
Harden received the concussion after a devastating blow to the head from Metta World Peace’s elbow. World Peace had just dunked the ball in traffic, and when running back to the end of the court in celebration, he threw his left elbow into the back of Harden’s head.
Harden left the game and was unable to return. World Peace has since apologized for the incident, but potentially faces a major suspension.
According to new NBA concussion rules, the third year standout will have to pass a series of rigorous tests before he can return to action for the Thunder. Oklahoma City is slotted to begin post season play this weekend.
