main event fights not the whole main card so the torres fight would still be 3.
Per the NSAC the criteria is not just where a fight is on a card that makes it eligible, they laid out several different qualifications and a fight only has to meet one of them.
It basically has to be a big fight for the weight class, a main event or a title contenders fight. Im not saying they will go wild with this but quite a few fights could
qualify to be five rounds.
