I wouldn't be so hard on Vitali, it's commonplace in all sports for injury to be the cause of retirement or inability to play. Boxing is no different and considering the physicality and the degree to which the fighters train, it's a miracle we don't get more injuries or postponements. Ok, thats 3 cards for 3 weekends that have been wiped out in a row but I can't remember a hat trick like that in my years of boxing.
