O’Driscoll and D’Arcy join forces against Glasgow
Shane Horgan and Denis Hickie miss the game with slight injuries as does Malcolm O'Kelly but all three are expected to be fit for the Celtic Cup quarter-final in three weeks time.
Wingers Kieran Lewis and Gary Brown form a strong back three alongside full-back Girvan Dempsey, while in the pack, Reggie Corrigan will captain the side.
Leo Cullen and Ben Gissing are named at second row with Keith Gleeson starting at wing-forward.
Elsewhere, there were contrasting fortunes yesterday for the Humphreys brothers at the end of a frustrating season for both.
Ireland fly-half David has been forced to pull out of the Ulster line-out for tomorrow's final and crucial Celtic League game of the season when they face Llanelli at Ravenhill. Ulster need to avoid defeat to finish in the top eighth and land an away quarter-final against champions Ospreys.
Meanwhile, younger brother Ian has landed a lucrative full-time deal with Leicester Tigers.
"The opportunity to pursue my rugby ambitions with Leicester Tigers who are consistently a dominant force on both domestic and European fronts was impossible to turn down,'' said the 22-year-old Belfast Harlequins fly-half.
"The prospect of receiving coaching from Paddy Howard who has played fly-half at international level, Neil Back and the rest of the coaching staff including a full time kicking coach coupled with the attacking style of rugby Leicester play was ultimately the determining factors.
"Now that my playing future is decided, I am looking forward to concentrating my efforts on helping Belfast Harlequins secure the AIL league title."
