only downside tho is for instance for the next card jones/machida is the main event and mir/nogueira is co main event
so mir and nogueira right now are training for 3 round fight
but if jones or machida get injured before the fight and pull out and no one is able to replace em, then mir vs noguiera becomes main event and is a 5 round fight
sucks for the fighters tho that way but usually unlikely but it has happened b4 nh
