In the back-row Kelly Brown moves to No 8 as Semo Sititi has had to head home briefly to Samoa through a family bereavement. Andy Rennick will start at blindside flanker and Andy Miller at openside flanker instead of Wayne McEntee.
Border Reivers head coach Steve Bates said: "We're very much looking forward to the Ulster game. We're very aware of their strengths and under no illusions that this is going to be a very tough battle but one we'll relish."
