type in ''angel of death'' in youtube i think it tells you what happened to him.
The third guy's name is Abdulrahman Al Shoaibi and he survived. The game is from Oct 20th 2005 between Al-Raed and Hajer Al Shaibi. He had a seizure following a blow to the head, which triggered involuntary movements - Much like when a boxer is knocked unconscious yet still tries to punch and continue. Rumour is he was taken to hospital were he recovered and in fact played the next game for Hajer.
(he lived :P)
