David Humphreys is set to make his first appearance of the season this evening as Ulster A travel to Old Belvedere for an interpro clash with Leinster.
The former Ireland outhalf has missed Ulster's start to the Magners League campaign after picking up an ankle injury in training.
Humphreys starts beside Kieran Campbell at half back but is expected to play only 40 minutes, enough to prove his fitness before next week's league clash with Leinster at Ravenhill.
Winger Simon Danielli and centre Seamus Mallon also start after featuring in the defeat against Llanelli last weekend.
Centre Darren Cave is given a chance to bring his club form to the provincial stage, having scored eight tries in his last three starts for Belfast Harlequins, with his club colleagues Paul McKenzie and Mark Kettyle completing the back division.
There is an inexperienced pack with Thomas Anderson, Chris Henry and David Pollock in the back row.
Tim Bark and Malone's Filo Paulo are at lock while Niall Conlon, Stuart Philpott and Declan Fitzpatrick form the front row.
Leinster have picked a young side which includes Irish U-20 grand slam winning full back Felix Jones and Argentinean prop Juan Francisco Gomez.
In the Ulster Senior League tomorrow City of Derry travel to Deramore Park.
Having already claimed the scalp of Ballymena, confidence is high and young scrum half Michael Heaney is given a chance to impress while Greg Mitchell returns to his former club.
Quins are defending an unbeaten record in the league and are set to rest Andy Ward while five players are on Ulster A duty.
Ballynahinch host Instonians but are without Stuart Lamb as he has picked up a knock as have Stuart Megaw and Mark Scott.
Mark Wilson moves into the second row for Inst with James McCullough replacing him at flanker. Andrew Harper partners Mike McKeever in midfield.
Ballymena and Malone are both weakened for the clash at Eaton Park while Dungannon travel to Banbridge.
Queen's have a depleted side for the Dudley Cup opener with UCD at the Dub although Mark Robinson and Ian Whitten could be available if they don't play 20 minutes for Ulster A.
