Weeks after the concussion-producing elbow that Metta World Peace of the Los Angeles Lakers threw at Oklahoma City Thunder guard James Harden, the two men will take the floor again tonight against one another in the playoffs. The reunion may not be as friendly as once anticipated.

“He doesn’t start,” World Peace explained. “I only fist-bump the starting five. I don’t fist-bump subs.”
