Ireland international wings Tommy Bowe and Andrew Trimble will start for Ulster in a pre-season game against Edinburgh at Goldenacre on Friday night (6.30pm).
Ireland coach Joe Schmidt and his management team will closely monitor their progress ahead of disclosing the 31-man World Cup squad to the players at Carton House on Sunday.

He is selected on the left wing, Bowe starts on the right, with fellow international, Craig Gilroy, named at fullback.

Ian Humphreys and Paul Marshall, who scored a try in last week's run out against Leinster, continue in the halfbacks. In the front row Andrew Warwick and Wiehahn Herbst start either side of Rob Herring who is selected at hooker.
Dan Tuohy and Franco van der Merwe are paired in the second-row with Clive Ross, Sean Reidy and Robbie Diack picked in the back-row.
