Justyn Hugh will face veteran Dean Francis for the Welsh light-heavyweight international Masters title at the Newport Centre on Saturday.
The 28-year-old from Newport is unbeaten in his 12 fights as a professional.
Francis is a former British, Commonwealth and WBO inter-continental light-heavy champion.
"This is a real step up in class for Justyn," said Hugh's St Joseph-based trainer Tony Borg.
"He has never fought at this level before but Justyn set himself the target four or five years ago of winning the Welsh, Celtic and British titles."
Francis beat Talywain's Jeff Evans last time out to win the Welsh light-heavyweight belt.
But the 38-year-old from Basingstoke has a record of 31 wins (25 knockouts) and only four defeats in a career that stretches back to 1994.
A victory for Hugh over Francis would put him in contention for a British title fight.
Newport's Craig Woodruff, Cardiff's Lewis Patterson, Luke Osman of Treharris and Aberdare light-middleweight Taz Jones, who returns after three years out of the ring, all fight on the undercard.
