Japanese superstar Naoya Inoue has revealed that he suffered a pair of fractures around his right eye, as a result of the toughest fight to date of his pro career.

This past Thursday, Inoue came away with the win in his punishing World Boxing Super Series bantamweight final with a twelve round unanimous decision over former four division champion Nonito Donaire.

Inoue was a heavy favorite to win the fight. Donaire bought the fight to him without fear. He was able to cut Inoue badly above the eye in the second round. And he rocked Inoue in the ninth round. Inoue was able to recover and dropped Donaire with a vicious body shot in the eleventh.

Following the fight, Inoue had a further examination on the right eye on Friday and the fractures were revealed.

Inoue, who added the WBA super bantamweight championship to the IBF crown he held before, did not give a timeline for his recovery but he will apparently not need surgery.

"I felt something was wrong when I began seeing double," Inoue said. "I've been told it will not affect my next fight. For the time being, I'm going to take it easy."

Inoue's next fight is scheduled for next spring. His plan now is to resume training after getting the results of a follow-up examination a month from now.

It was announced, following the fight, that Inoue had signed a multi-year promotional deal with Top Rank.
