The planned super bantamweight 10-rounder between Former International Boxing Federation super bantamweight champion Yukinori Oguni of Kadoebi Boxing Gym and former Oriental and Pacific Boxing Federation ruler Shingo Wake of FLARE Yamagami Boxing Sports Gym on Apr. 28 at Tokyo’s Korakuen Hall was cancelled due to Oguni’s right fist injury during training, according to Kadoebi gym.

The fight had attracted a lot of attention among boxing fans as each of them regarded the bout as ‘’a survival battle’’ in his quest for a world title challenge.

Oguni will receive an operation of the injured fist so as to heal the injured part completely. Kadoebi gym, an organizer of the event, said on Feb. 16 it is seeking another main event in their stead on that day.

Both first fought in March 2013, and Wake stopped then OPBF champion Oguni in the 10th round to capture the title. After successfully defending the title five times, southpaw Wake fought Jonathan Guzman of Dominican Republic in July 2016 for the vacant IBF super bantamweight title only to be stopped in the 11th round.

Meanwhile, Oguni dethroned Guzman in December 2016 but lost the title to Ryosuke Iwasa of Celes Boxing Sports Gym in his first title defense in September 2017.

The 32-year-old Oguni, who has a 21-2-1 win-loss-draw tally with eight KOs. is currently ranked fourth in the division by the World Boxing Association while the 33-year-old Wake, who has a record of 27 wins, including 19 knockouts, against six losses and two draws, is ranked 15th by the World Boxing Council.
