Andrew Selby's second professional fight will be against Hungarian Jozsef Ajtai in Bristol on Saturday.
The Welsh flyweight, 26, beat Tanzanian Haji Juma with a fourth-round stoppage on his professional debut in October.
Ajtai, 18, has triumphed in all 10 of his bouts since making his debut in May, winning six by knockout.
The fight at Bristol's City Academy will be on the undercard of the British middleweight title fight between Nick Blackwell and Jack Arnfield.
Selby, brother of IBF world featherweight champion Lee, won European Championship gold medals in 2011 and 2013 and claimed a silver medal at the 2011 World Amateur Championships.
