UUJ surprised Ulster Champions Donegal in Section C of the Power NI McKenna Cup while Derry edged out Cavan.
Donegal and UUJ were 0-5 to 0-5 at half-time at Letterkenny but after the home side moved two ahead, UUJ bossed the final quarter to win 0-11 to 0-9.
Derry led 0-7 to 0-5 at half-time but Cavan hit four unanswered points as Derry's Eugene Scullion was sent-off.
However, points from Conleth Gilligan, Mark Lynch and Niall Holly helped Derry win 0-13 to 0-12 at Celtic Park.
Donegal gave debuts to Gary McFadden and former Cork panellist Ciaran McManus although the Munster man was substituted at half-time.
Chris Clarke hit three of UUJ's first-half scores with Ciaran Donnelly also on target for the Poly while Dermot Molloy notched four of Donegal's opening-period points in an evenly matched first 35 minutes.
Substitute Patrick McBrearty hit two quick points after half-time as Donegal looked set to take control.
However, UUJ responded with four unanswered points with Diarmuid McNulty, Ciaran Donnelly and CJ McGourty among the scorers.
Ryan Bradley and Molloy scores drew Donegal level again but two late McGourty points saw Jordanstown edging the verdict as the home side had Neil Gallagher sent-off in injury-time after a second yellow card.
At Celtic Park, Cavan led by three points early on but could not make full use of their wind advantage.
The Oak Leafers recovered to enjoy a 0-7 to 0-5 lead at half-time thanks to points from Caolan O'Boyle (four), Enda Lynn, Emmett McGucken and Eoghan Brown.
Raymond Galligan (2), David Givney, Niall McDermott and Ray Cullivan were the Cavan scorers.
Cavan started the second half by scoring four unanswered points and Derry suffered a further setback when full-back Scullion was sent-off midway through the second half.
