No such feud existed between Rousey and McCann, though both are former Olympians, but the fight still went down with controversially. Rousey scored a TKO in just 66 seconds — the fastest knockout in the brief history of women's UFC — but referee Herb Dean took the brunt of the fans' anger afterward.
Rousey kneed McCann in the midsection, immediately sending her to all fours on the canvas. Rousey followed with a few weak punches to the head, but Dean stepped in right away to stop it.
Dean is not a fan favorite among referees, with a reputation for stopping fights too early. Literally just three weeks ago, UFC President Dana White criticized Dean for an early stoppage in UFC 169's fight between Renan Barao and Urijah Faber.
"He rarely ever makes mistakes, but he made a mistake tonight," White said of Dean following the fight in Newark, N.J. the night before the Super Bowl. "Faber was blocking those shots; he gave the thumb’s up."
UFC fans might beg to differ on Dean, though he certainly is heavily experienced and White has always backed him. So he got the call for Rousey versus McCann and again we got a little controversy.
You can watch the video above and make your own call, but let's be fair, it looked like Rousey would've been able to pounce on McCann and beat her with ground and pound if the fight had continued.
But the commentators on Twitter were not kind to Dean ...
It'll be interesting to see who Rousey takes on next. Cris "Cyborg" Santos, who easily ended the Gina Carano phenomenon, is the obvious "super fight" but the two fight at different weight classes, so it might be tough to work out.
