Hekkie Budler kept a firm grip on his WBA and IBO mini flyweight titles with what was a unanimous points win over Jesus Silvestre at the Salles des Etoiles.
The South African cruised to a 117-110 and 115-112 (twice) win on the officials cards despite being caught low in the second round by the challenger.
Argentinian Silvestre, who was forced to shed pounds after the weigh-in due to scaling over the 105lb limit, is now likely to move up to flyweight.
Earlier, British heavyweight Hughie Fury produced a career-best performance in Monaco to push his impressive record to 15-0.
The 20 year-old, who once harboured hopes of beating the great Mike Tyson’s record of being the youngest ever world champion, was in dominant form after returning from a long injury lay-off.
Fury inflicted just a second loss on the tough Ukrainian in 26 professional bouts as the ringside judges carded 98-92, 98-91 and 97-92 in his favour after ten rounds.
Also on the bill, compatriot Lee Haskins picked up the vacant European bantamweight title with a technical decision win over Omar Lamiri.
The fight was halted after eight completed rounds as Haskins begun his second reign as champion with a 79-73, 78-74 (twice) triumph.
Haskins is now in line for a potential world title shot in the summer of 2015.
