Murice Smith has long been known as one of the best kickboxers of all time, reigning the ranks of the World Kickboxing Association (WKA) for many years. His biggest succes, however, came when he became the first kickboxer to become UFC champion twice. His wins at UFC enabled him to take other big MMA fights against greats of the octagon like Mark Ruas and Bas Rutten. His last fight was recorded in 2013 and he is believed to be retired for good.

When the WKA (World Kickboxing Association) changed ownership to Briton Paul Ingram from founder Howard Hanson, the Mirage hotel was host to one of the most spectacular WKA kickboxing events in its history.
