Mackenzie Dern’s UFC debut will headline FS1 portion of UFC 222 fight card AT STRAW WEIGHT vs Ashley Yoder... personally, I really hope she does well . She has very little experience as an MMA fighter. It is interesting though how she could likely beat every girl in the division if she can manage to Ronda Rousey her way to the top. Meaning I believe she could beat the champ if it went to the ground. Girl is an ADCC and no gi BJJ World Champion. YOU MAY HAVE DIF OPINIONS SO LETS HEAR THEM SHERDOG!
