The Italian Giuseppe Quartarone has been confirmed as the referee for the world heavyweight unification fight between New Zealander Joshua Parker and Briton Anthony Joshua in Cardiff at the end of the month.
Quartarone has refereed a world heavyweight title fight before, being in charge of Alexander Povetkin's WBA title victory over Cedric Boswell in 2011.
"We're very happy with the officials that have been appointed," Barry told Sky Sports.
"We've got three judges - one from New Zealand, one from the UK, one from the United States.
"We've got an Italian referee. We signed off on those officials [at the beginning of March]. We're very happy with what the various sanctioning bodies have appointed for us."
