Brown put a big beating on Wonderboy. His "kickboxing" career is also mostly a joke. For example most of those fights were no head-strikes, the rest were in Chuck Norris' private trash league. He even got KO'ed by Raymond Daniels but it mysteriously wasnt ruled a KO loss, the video is on youtube. As for the UFC no he hasnt taken a lot of damage but Brown beat his ass and Ellenberger dropped him with one of the only 5 shots he landed. Wonderboy does not have great head movement but he's a great fighter. Dont be surprised if Woodley does chin check him.
