The three Kameda boxing brothers, who have been indefinitely banned from fighting on home soil after the Japan Boxing Commission refused to renew licenses to their gym, are scheduled to fight in an event together in the United States in mid-April, an informed source said Friday.

WBO bantamweight champion Tomoki Kameda, the youngest of the trio, has reached an agreement to fight WBA bantamweight champion Jamie McDonnell of England in a title unification match.

Daiki, the second oldest, will climb in the ring for a nontitle match, his first since his controversial super flyweight title unification bout in December 2013.

The oldest brother, Koki, is expected to fight a nontitle match at super flyweight as he aims to win world titles in four weight categories.

"I want to focus and just get in the best condition," said Tomoki before taking off from Narita airport to train in Miami.

Daiki, who intends to move up a notch to bantamweight, said he hopes to get another chance at a world title.

"I'd like to become world champion one more time," said Daiki.

The JBC refused to renew licenses to the Kameda Gym's chairman and manager after taking issue with the dubious manner in which Daiki retained the IBF super flyweight crown in December 2013.
