Apparently he stretched out for a ball, got his studs stuck in the ground, his knee went the wrong direction, Scott Parker then landed on the leg snapping it the wrong way. Scott Parker went off the pitch too, more because of what he had just seen and done not due to injury, sounds a complete accident but disgusting. And apparently Kamara wouldn't comment on exactly what happened because he said it was "making him feel sick."
Fookin hell, hope he's not out too long.
