Offaly trio Shane Tierney, Billy Carroll and Jack Bryant and Laois' Mark Barry lost out.
There's further local interest in next week's Sigerson Cup final between UL and NUI Galway.
Portlaoise's Frank Flanagan was introduced as a first-half substitute as the Munster side, led by David Clifford, advanced to their first decider since 1997.
In doing so they ended the hopes of a further four local players, Offaly trio Shane Tierney, Billy Carroll and Jack Bryant and Laois' Mark Barry, who were on the losing DCU panel last night in Rathkeale.
Clare’s Emmet Mc Mahon, Kerry’s David Clifford and Donal O’Sullivan and Mayo’s Connell Dempsey all on the scoresheet for a UL team that was missing Eoghan McLaughlin and Stefan Okunbar.
Galway’s Robert Finnerty and the Offaly pair of Shane Tierney and Bill Carroll all grabbed points for DCU.
UL will face NUIG in the Final next Wednesday after Maurice Sheridan’s side overcame MTU Kerry Campus by 3 points after extra-time.
Cathal Donoghue and Rory Egan will be in the Connacht school's side. They both started in that victory last night.
