Looking at the video a few times, I would bet a shiny new penny his neck broke on impact. Getting manhandled by the "rescuers" probably didn't do him any good either. 50/50 he lived/died
He did move a little when he was on the dirt before the people dragged him. He raised his head just a bit. Lucky the bulls horn did not get him. He looks like a rag doll when the bull so easily tosses him over his head.
