Heather Hardy is out of her BKFC 61 headlining bout with Christine Ferea, but that appears to be the least of her concerns. Hardy on Monday shared a troubling health outlook in a grim Instagram post as the former boxing champion revealed “too much brain damage” from fighting has severely impacted her vision. Hardy had been set to make her BKFC debut and challenge Ferea for the promotion’s women’s flyweight championship this Saturday. Hardy said she experienced blurred vision a few days after her title-fight loss to Amanda Serrano last August. At the time, Hardy figured she just needed time off to recover properly, six to eight months. Hardy said financial woes pushed her to accept an offer from BKFC and after a month into training for Ferea, “everything got worse with my sight.” “I was down to 123 pounds because I couldn’t eat, I wasn’t sleeping, I was so weak,” Hardy wrote on Instagram .
