MMA fighters crossing over to boxing have rarely seemed to meet immediate success. Anderson Silva lost his pro debut, as did Mike Perry, and even Israel Adesanya. Of course Conor McGregor got a chance to perform on boxing’s biggest stage as one half of a PPV main event against Floyd Mayweather Jr.
Otherwise, Joe Duffy & Kimbo Slice had some surprising success in the ring, each putting together a 7-0 unbeaten record a variety of low level journeyman opponents. Perhaps the most notable crossover success story comes in the form of Clay Collard, whose seemingly less than impressive 9-4-3 record as a boxer has been largely built against promising prospects on the rise.
