The starting line-up shows two changes from that which was defeated by Connacht at the Sportsground last Saturday. Paul Steinmetz sustained a leg injury in that match and while his scan has come back clear he was not available for selection this week and is replaced by James Topping, Matt McCullough is also ruled out though injury though he has also had a scan which is clear. Bryan Young replaces Justin Fitzpatrick at loosehead.
David Humphreys needs just three more points to become only the second player ever to score 500 career points in the Celtic League - the other is Gavin Henson - and needs just seven points to pass Henson's career aggregate record of 503 points.
The last four Celtic League meetings between Ulster and Glasgow Warriors have gone in favour of the home side on the day.
