I read that it was a sprained MCL, not a torn one, and sprained is supposed to be less severe (hopefully). So I guess all we can do is hope that it gets better quick so that shows can return to normal quality, OR we can hope Jon realizes how shitty this is going to be for people and makes it up setlist-wise. I'd rather have a shit-bricks-fantastic setlist and Jon in a chair than a short, vanilla show with Jon trying to move around a little.
