MMA: Has Ronda Rousey revealed why she lost to Holly Holm?

Arguably UFC's biggest drawcard was sent sprawling to the deck by Holm in one of the biggest upsets the sport had ever seen.

And in her first interview since the clash, the 28-year-old fuelled speculation she sustained a concussion early in the first round.

She told ESPN Magazine's Ideals of the Year edition: "I got hit in that first round. … I cut my lip open and knocked a couple of my teeth loose. I was out on my feet from the very beginning.

"I wasn’t thinking clearly. I had that huge cut in my mouth and I just spit [the blood] out at my feet. Then they brought the bucket over and I’m like, ‘Why didn’t I spit it in the bucket?’ I never spit on the ground.

"It was like a dumbed-down dreamy version of yourself making decisions. … I was just trying to shake myself out of it. I kept saying to myself, ‘You’re OK, keep fighting. You’re OK, keep fighting.'"

Rousey is unsure of when she will have a rematch with Holm, saying it could be six months until she eats an apple again, and has hinted another loss to Holm could be last fight.
