Here's my understanding of the situation. Johnny got a very bad back spasm during on the of the practices on Saturday. He was barely able to walk afterwards, but has been receiving physiotherapy (massage, electrode therapy, etc.), which has helped a little bit. The affected area is between his shoulder blades, which is obviously critical to rotation. I belive it is most problematic for him on spins.

He is receiving care, so let's all hope that he continues to get better and is able to skate well tonight.
