Damien Cassidy's inexperienced Derry side lost to UUJ
UUJ beat Derry 0-13 to 0-10 in Sunday's Gaelic Life McKenna Cup Section A game at Ballinascreen.
Derry led 0-7 to 0-4 at half-time but UUJ fought back to win and put a major dent in Derry's hopes of making the semi-finals of the competition.
Ciaran Donnelly scored eight points from frees for UUJ, three in the first half and five in the second period, and they next play Fermanagh on Wednesday.
Seamus Bradley top-scored for Derry with three frees.
The Oak Leafers drew their opening game against Fermanagh last week and now face Donegal next Sunday with only one point from their opening two fixtures.
Adrian McGuckin's UUJ side lost to Donegal last week but still have a chance to qualify as they prepare to head to Enniskillen on Wednesday night.
