In the end, nothing actually happened.
Yes, Rockets swingman Trevor Ariza did wait outside the Mavericks locker room for Dallas center Salah Mejri last night. And by the way, teammates James Harden, Patrick Beverley and Eric Gordon also were there, ostensibly to back up their teammate.
And, yes, it sure looked like Mejri had every intention of meeting Ariza in the American Airlines Center hallway until Mavericks security and assistant general manager Keith Grant calmed Mejri down and steered him out to the player parking area.
No confrontation actually occurred, but that doesn't mean Ariza's and Mejri's actions, or intended actions, will be ignored by NBA officials.
