IMO, it looked like Flores was faking being KO'ed to fish for a DQ. The punch didn't seem seriously after the bell, so it's really not in DQ territory, whether faking or not. If the referee thinks you're faking, and you don't get up, then you're KO'ed. If a KO blow comes appreciably after the bell, then it would be a DQ. If a KO blow happens barely after the bell, then it can be handled more similarly to any accidental foul, i.e. no contest if 4 rounds haven't completed, otherwise go to the cards. In this case, the referee must have thought Flores was trying to exploit the situation.

If the blow had landed later, and the referee still ruled it a KO, I would feel as though he was favoring Rigondeaux. Referees are often pretty reluctant to allow a highly ranked, undefeated fighter catch his first loss under controversial circumstances. If someone KO'ed Mayweather 1 second before the end of the fight, I wouldn't be surprised to see the referee pick him up and just rule it a knockdown.

It happens frequently anywhere & everywhere & has so since 10 seconds alert was introduced. Guys simply seem to go for their life to score KO & in doing so...they lack concentration. Seen guys who were well ahead on points get done in last 10 seconds of a round.
