Article says he has no serious injuries.
According to his manager, Anca Cláudia Guedes, JDS remembers nothing after the knockdown in the third: "He went to autopilot mode after that strike, he doesn't know what happened. We've told him now, but he thought he had been knocked out in the third and the fight ended there. He had no idea he made it into the fifth round or even that he gave an interview in the end".
Looking calm, he said that bigger than the pain from the wounds is the pain he is feeling in his heart. "I'm feeling well now. I came to the hospital just to get some stitches in the cut I got. The pain is just in my heart for not having a good performance. Now I gotta go back to the gym and train even more, dedicate myself more to come back stronger than ever and maybe someday fight for the belt again. If God wants it, I'll be able to honor the support of all who believe in me".
