In March 2017, Mosley announced that he would fight on against unbeaten Russian prospect Magomed Kurbanov (10-0, 8 KOs) at DIVS in Ekaterinburg on May 5, 2017. The fight would take place at light middleweight in a 10-round bout and contested for the vacant WBO Inter-Continental title. In April, RCC Boxing Promotion revealed that Mosley had picked up a hand injury whilst training. The fight was pushed back to take place on September 9, 2017 instead. On June 29, 2017 it was reported that Mosley had an unsuccessful surgery in his back, which required him to undergo another surgery. The fight was pushed back again to December 2017; however, because Mosley could not guarantee he would be fully recovered, the fight was called off.
