Ulster coach, Mark Anscombe, has made seven personnel to the team that lost to Newport Gwent Dragons last week for tomorrow's clash with Glasgow Warriors at Ravenhill (kick off 19:05).
One of the changes was forced as Ireland winger Andrew Trimble was unavailable for selection having suffered a finger injury.
He will have surgery tomorrow morning and is expected to be out for between four and six weeks.
David McIlwaine starts on the right wing in place of Trimble, while Darren Cave returns to the backline at outside centre, with Luke Marshall moving inside to 12.
Michael Allen is selected on the left wing, with Ian Porter picked at scrumhalf in place of Paul Marshall who is named on the bench.
Declan Fitzpatrick is selected at tighthead, while in the back row Roger Wilson moves from Number 8 to blindside, Sean Doyle is named at openside with Nick Williams starts at Number 8.
Iain Henderson is named among the substitutes and will make his first appearance for Ulster this season if he comes on.
Anscombe said: "A good squad is one that can respond to poor performances and bounce back.
"What we have to do is to right the wrongs and get our accuracy a bit better than it was last week. If we can get that right then we can get a reasonable performance."
The game will be shown live on BBC 2 Northern Ireland and on the BBC Sport website.
