I posted this in the game thread, but since this is going to get a lot of questions from people not watching, I'll post it here:
I couldn't tell how low on the back TJ got hit. That could have been a kidney shot. That's a ing paralyzing blow if you get hit hard. He was kicking his legs, and moving his arms. He may be in the locker peeing blood right about now. I hate to say it, but I hope so. He'll come back soon enough from that.
It looked like Davis' hit him with a forearm in the back, just around the bottom of the ribcage. That's the right area for a kidney shot. I'm still hopeful from the way he was moving around that it's not the spine.
