Tyrone McKenna and Sean McComb have been handed late opponent changes ahead of their Feile appearances.
McKenna was due to face Zhankosh Turarov for the WBO intercontinental lightweight title at Falls Park on August 6.
But now the West Belfast boxer will fight Mexican Jose Felix Jr for the belt next month.
Felix Jr has won 39 of his 44 pro bouts to date, including 30 wins by stoppage.
One of his four defeats was against Bryan Vasquez for the WBA Interim world super-featherweight title.
McKenna said on Twitter: “Turns out Turarov is still running scared…but got an unreal replacement a few weeks ago. Jose Felix Jnr…I’ll be out warring the Mexican.”
It is the second time McKenna vs Turarov has fallen by the wayside.
The pair were due to meet in Dubai on April 3 on the undercard of Carl Frampton vs Jamal Herring, but the fight was pulled at the eleventh hour after Turarov withdrew.
Meanwhile, Belfast super-lightweight Sean McComb has also been handed a change of opponent for the same show.
McComb will take on former world title challenger Vicente Martin Rodriguez after initially being paired with Craig Woodruff.
The Public Nuisance tweeted: “Different opponent same result! Let’s get it.”
It has also been announced that Cain Lewis will make his professional debut at the Feile.
The August 6 show at Falls Park will be headlined by Michael Conlan’s massive all-Irish showdown with former world champion TJ Doheny.
