Emergency knee surgery for my brother

hello, this fundraiser is for my brother Corey Austin. He blew out his knee 4 years ago and the surgeons decided that he needs immediate surgery to repair his patella tendon that has ruptured. He’s been walking on said injury for 4 years. He loves to compete in boxing, kickboxing, and MMA. Please help us with costs of the surgery itself and bills needed so he doesn’t get massively damaged financially. Thank you all.
