The Boston Celtics are hosting the New York Knicks, and in the mid third quarter Boston forward Glen Davis spun in the air (it appeared to be a full 360) and landed badly, hurting his left knee.

A replay didn’t look particularly bad — no disgusting ‘obvious’ injury or anything — but Davis fell to the ground and stayed there, in obvious pain. He was eventually helped off the court and brought to the locker room. No word on how serious it is.

8:55 p.m. ET update: It’s just a strained quad muscle.
