Rowdy previously said she went into the 2015 bout against Holm with a concussion.
"It was a very high-profile result. You need a defeat of a clear favorite for something like that. If Ronda wasn't perceived to be much stronger, there was no upside. But I fought better that night. As for concussions - all fighters have had them if you perform long enough.
Look at my boxing career - I've definitely gotten concussions. There's no way I've ever used that as an excuse to lose. I guess it's so hard for her to admit I was better. She was a deserved champion. But not that night," Holm said at the press conference.
