I was in my partner's guard, and he acquired a shoulder crunch on my right arm. He hip bumped me on toward the left side, which is the "wrong" side (toward the direction of my free arm with a post). His right leg was heavy and pinning my left knee to the mat, and I stopped the sweep with my arm post, but my left knee's MCL still tore in the process.

I wonder if my MCL popping was based on bad positioning on my part, or just bad luck. I'll probably be out from training for a month or two but I want to make sure I avoid this in the future!
