This picture was tweeted by @lexmcmahonMMA, the president of Alchemist Management. We don't know who actually took this picture at UFC 155 since there's absolutely no watermark. However, we do know that it's an extraordinary example of one human force-feeding another human a knuckle sandwich. If anyone out there knows the photographer of this picture, let us know and we will give him/her a superfluous amount of credit in this article. In the meantime, we're just going to stare at this magnificent visual evidence of the dominant performance Velasquez placed on dos Santos at UFC 155.
