Jono Carroll suffered the second defeat of his career as he was outpointed by English fighter Maxi Hughes on Wednesday night.
The super featherweight contender, whose only other defeat was at the hands of the impressive Tevin Farmer in a world title bout last year, lost on a unanimous decision to ever-game Hughes, who secured a 97:93, 96:95, 96:95 decision.
Carroll had been working back towards another world title shout, having dispatched of former world champion, Scott Quigg, earlier this year ahead of the coronavirus pandemic.
Elsewhere, on the behind closed doors card at the Production Park Studios in Yorkshire, former Irish amateur champion and European Games bronze medallist, Sean McComb, maintained his march towards the top of the lightweight division with a unanimous points win over Siar Ozgul.
The Belfast fighter remains unbeaten in the professional ranks following his 11th straight victory.
Dubliner Pierce O'Leary was also fighting on the undercard of the Carroll fight and made it four wins from four outtings in the paid ranks with a comprehensive fourth round knock-out win over local fighter Jacob Quinn.
