Brock Lesnar is a once-in-a-lifetime wrestler. Hes the perfect combination of amateur wrestling credentials, the ideal physique that Vince McMahon loves, the intimidation factor, and the actual strength to lift men much heavier than him onto his shoulders. Though he has never been the best at promos, that was never important to him anyway; for him, actions definitely spoke louder than words. At the same time, Brock Lesnar has enjoyed one of the most protected careers in WWE history. In his short WWE career, Lesnar has won the vast majority of his matches, and when he did lose, for the most part, it was either because he wasnt the one defeated (i.e. in handicap matches, tag matches, Triple Threat matches, etc.), via disqualification (because, again, Brock Lesnar is a Beast), or due to interference or other controversial circumstances. In short, Brock Lesnar has rarely lost clean, and when he did, it was a big surprise. This article will list ten of those instances in which Brock Lesnar lost without any controversy. These moments in WWE history are few and far between, and include both PPV matches and regular RAW and SmackDown shows. They also include some of the best matches in his career. As an additional note, this list will not include Lesnars most recent loss to Seth Rollins and Roman Reigns at WrestleMania 31. That is because 95% of Lesnars match was a singles match, and Rollins just came in at the end, cashed in his Money in the Bank Briefcase, and Curb Stomped both Lesnar and Reigns, before pinning Reigns to capture the WWE World Heavyweight Championship. That is clearly an unclean match finish, and might as well be considered as outside interference. With arguably one exception, in all of these cases, Lesnar was pinned or tapped out without any controversial circumstances at all.
