Northern Irishman Carl Frampton will face Kiko Martinez for the IBF super-bantamweight title in September.
The fight will be the second time that the two have faced other, with Frampton winning the first contest by ninth-round stoppage, but Martinez responded by winning a world title two matches later.
However, after a couple of successful defences, Martinez has agreed to fight Frampton again on September 6, with the bout almost certainty taking place in Belfast.
The 27-year-old had put himself in line to face WBC titlist Leo Santa Cruz, but with the Mexican in talks with Scott Quigg, the rematch between Frampton and Martinez was made for the autumn.
