Watch Ronda Rousey Get Knocked Out by New Champ Holly Holm

It was easily one of the biggest upsets in the history of sports.

Nobody gave Holly Holm a snowball's chance in Hell of beating Ronda Rousey, but Holm not only won, she knocked Rousey out.

Holly, a world champion boxer before she switched to MMA, knocked Ronda out with a kick to the face in the second round to win UFC 193, and the women's bantamweight championship.

A bummed out and depressed Rousey finally broke her silence Sunday night with an Instagram post thanking everyone for their “love and support,” and vowing, “I’ll be back.”

Ronda's time off will include filming a remake of the ‘80s classic "Road House". She’ll play the lead role made famous by Patrick Swayze.
