long time lurker here, finally decided to register. i've been capping mma for about a year and still consider myself a newb. so i apologize in advance if my questions are common knowledge, or just plain stupid. 
my question is, what happens when a result is later changed to a NC? specifically, i am anticipating the thiago silva/brandon vera fight to be changed to a NC. will the sportsbooks try to recoup monies they paid out on silva, and vice-versa on vera? or will they keep it status quo?
