Paddy Gallagher suffered a shock exit on the opening night of the Irish Elite Championships in Dublin.
Commonwealth Games gold medallist Gallagher, who lost in the Ulster final to Willie McLaughlin, went down 6-1 to Danny Quinn of Glasnevin.
This latest setback leaves the Gleann man with little hope of making the Olympics next year.
Ulster champion Tyrone McKenna and fellow Belfast man Sonny Upton will clash today for a place in the semi-finals
Last night McKenna, who claimed the Ulster light-welterweight title last week in the Ulster Hall, was too classy for Tommy Dwyer, comfortably winning 3-0.
Upton, from Holy Family, immediately followed McKenna into the ring and duly impressed as well with a fine 5-1 decision over former three-time Irish finalist Eamonn Tuohy.
Now McKenna and Upton face each other for the right to meet either former champion Phil Sutcliffe or Stephen Coughlan in next weekend's last four duel.
Beaten Ulster Elite finalist Sean McComb of Holy Trinity progressed when he defeated Danny Coughlan 4-1 at 56kg.
Meanwhile, Olympic silver medallist Kenny Egan and World Youth champion Joe Ward look set for a mouth-watering light-heavyweight clash on finals night in two weeks time.
Both men received byes into next week's semis and were kept apart in the draw with Egan to face either Thomas Roohan or Brian Fitzpatrick and Ward set to meet the winner of tonight's clash between Davey Joe Joyce and Sean Allen.
