Metta World Peace knocked James Harden out of a Sunday afternoon game at Staples Center. It's not clear when Harden will be able to return to the court.
The Oklahoman reported that Harden was diagnosed with a concussion after taking World Peace's swinging left elbow to his head during the second quarter of Sunday's game between the Oklahoma City Thunder and the Los Angeles Lakers.
As such, Harden will be subject to the NBA's new concussion policy, which mandates that Dr. Jeffrey Kutcher, a professor of neurology at the University of Michigan and the Director of the NBA's Concussion Program, must independently clear Harden before he can return to the court.
The Oklahoman reported that it "could be a few days" before Harden is able to receive said clearance and that he did not address reporters on Sunday. It's not clear whether he will be able to play in OKC's two remaining regular season games.
Harden was evaluated multiple times during Sunday's game and did not return to action. Harden was knocked from the game after posting 14 points, 3 assists and 1 steal on 5-for-7 shooting in 13 minutes.
The Thunder conclude their 2011-2012 regular season schedule by hosting the Sacramento Kings on Tuesday and the Denver Nuggets on Thursday. The Thunder are currently the No. 2 seed in the Western Conference, with a record of 46-18, and would face the Dallas Mavericks if the playoffs began on Sunday.
After the game, World Peace apologized for his actions and said that the foul was "unintentional."
Harden's close friend and teammate, All-Star forward Kevin Durant, called the play "unfortunate" during a televised halftime interview.
The Lakers went on to defeat the Thunder 114-106 in double overtime.
