Ismael Barroso suffered a damaging loss in Japan as he was stopped in the ninth round by the relentless Andy Hiraoka.
The 41-year-old, one of boxing's biggest punchers, was made to look his age as he struggled to cope with the fast pace set by his opponent.
The Japanese star is eager to make a significant impact at 140lbs and will have his eyes on securing bigger fights after an impressive win.
Hiraoka started with purpose, and did not slow down as his performance eventually caught up with the veteran super lightweight.
Barroso entered the fight in decent form after stopping Ohara Davies in January and pushing Rolando Romero close eight months prior.
British fans are familiar with the Venezuelan after he stopped Kevin Mitchell in 2015 before suffering a loss to Anthony Crolla the following year.
