John Thornett (49)
The soles of his boots are pointing to the sky and his shoulder is less than 10 centimetres from the ground. I'm trying to think of different possiblities for what happened next, but I can only think of one. i.e. his shoulder strikes the ground. IF that is what happened then it is an automatic red card.
His elbow strikes the ground first. It's quite clear when the gif ends just before that happens. As with many of these 'tip' tackles, there was nothing wrong with it. Moody's incident is obviously different.
