Somewhat of a controversy on the stoppage tonight but if you look at the replay her opponents elbow is definitely hyperextended and could have been dislocated.
Her complaining seems like a way to save face tbh and I can't blame her. Noone wants to be submitted that fast.
Here's a link to cage potato that has the fight.
I'm not a Mazz fan but I'm glad he called it early. Don't want to see anyone out for a pointless injury.
