Speaking about hitting the milestone, Andrew said: "Whenever I started my career I wouldn't have dreamed that I would get to 190 appearances for Ulster. Every game has been unbelievable, especially the matches at Kingspan Stadium on a Friday night. Paddy (Wallace) is a guy who I have a massive amount of respect for so overtaking his total means a lot. It's going to be a very special night for me."
Trimble will start on the right wing with Craig Gilroy selected on the left flank. Louis Ludik completes the back three and plays his 28th game for Ulster.
Luke Marshall and Stuart McCloskey continue their partnership in midfield, with Paul Marshall and Peter Nelson paired in the half backs.
Up front, Andrew Warwick and Wiehahn Herbst are selected either side of captain Rob Herring, who is named at hooker. Ireland international, Dan Tuohy, returns to the starting XV and starts alongside Peter Browne in the second row.
With Nick Williams unavailable for selection due to personal reasons, there is a change in the backrow, with Robbie Diack named on the blindside, Sean Reidy coming in at openside and Roger Wilson starting at the base of the scrum.
Ulster Head Coach, Neil Doak, has gone for a five-three split on the replacements bench. Forwards, Paul Jackson, Callum Black, Bronson Ross, Lewis Stevenson and Clive Ross are joined by backs David Shanahan, Sam Arnold and Rory Scholes.
Seats in the Memorial End Stand and Hughes Insurance Family Stand are now sold out, however, tickets remain available in all terraces and the Grandstand.
