Veteran point guard Derek Fisher, who is stationed in a stall next to Perkins, was asked what he thought of the altercation.
"I don't know if I'd call it an altercation," Fisher said. "These two teams have played just about more than anybody in the league in the last two years. There isn't much space on the floor to operate, so offensively and defensively, guys are going to be pumping and pushing and getting after it."
The Thunder and Mavs indeed have met frequently the past two seasons with eight regular-season games; two preseason games this season; and seven playoff games with two more to come by Saturday.
