Girl fight! Ronda Rousey bites Liz CarmoucheI guess there were rumors that during the rear naked choke Ronda bit Liz' arm. Of course that isn't true as Liz is showing Ronda her teeth marks.
I guess there's two explanations floating around. 1) Ronda's mouth guard was push asided and Liz’s arm pushed down on her teeth. 2) Ronda's mouth guard fell out during the submission attempt
Whichever the case, it wasn't intentional.
