Amanda Nunes pulled out of her UFC 213 fight because she was dealing with a chronic condition that didn't allow her to breathe properly ... according to the brawler herself.
Amanda posted a statement Sunday explaining her sudden withdrawal from her main event fight against Valentina Shevchenko , saying she suffers from chronic sinusitis.
She goes on to explain that she's fought with the condition before, but couldn't soldier on this time because she felt off balance and couldn't breathe at the official weigh-in. She also says UFC docs cleared her based on blood and dehydration tests .
