Kendrick Perkins injured his left knee during this collision with Stephen Curry Tuesday.A quick update on Kendrick Perkins' knee injury after watching the tape again this morning (and with the keen eyes of Brian Robb of our TrueHoop partner, CelticsHub): Perkins appeared to injure the knee when he collided with Golden State's Stephen Curry trying to set a screen to spring Ray Allen early in the third quarter.

Perkins' left knee bumps with Curry's leg as he tries to force the speedy defender to go wide to catch up with Allen. Perkins immediately grabbed at the knee, but stayed in the game until a timeout following a Boston made basket.
