Late in the second quarter Russell Westbrook dove on the floor for a loose ball as Metta World Peace tried to tie him up. Westbrook, an admittedly emotional player, took exception to it, flailed his arms around and a scuffle ensued.
Double-technicals were issued to both World Peace and Westbrook. The question was if World Peace dropped a knee towards Westbrook's groin, but it's pretty unclear as to if it was intentional or a result of Westbrook hitting the back of his leg.
Either way, with the past history between World Peace and the Thunder, it made for a tense moment in the game.
