Darren Cave returns to outside centre after a break so Tommy Bowe returns to the right wing with Andrew Trimble—who ran in a hat-trick last week—switching to the left wing.
Loosehead prop Tom Court returns to the front row to replace Andrew Warwick and Sean Doyle replaces the injured Robbie Diack in the back row, so Chris Henry switches to the blindside with Doyle on the openside.
Warriors head coach Gregor Townsend has made two personnel changes to the side that shocked Munster 22-5 at Thomond Park on Saturday with Peter Horne making his first start since June after nine months out with an anterior cruciate ligament injury.
Finn Russell switches from the midfield to outside-half in place of Duncan Weir—a position he has impressed in against Cardiff Blues and Newport Gwent Dragons—with Mark Bennett returning at outside centre after helping a Warriors side win the Melrose 7s last weekend with Alex Dunbar missing out with a wrist/thumb injury.
Ulster—who moved into second place in the table last week, helped in part by the Warriors’ win over Munster—have lost just one of their last eight league matches, which was a shock 28-23 defeat to Cardiff Blues at the Arms Park earlier this month, but have lost their last two encounters with their rivals for the meanest defence in the Pro12.
The Warriors have won their last four matches since a narrow 28-25 defeat to league leaders Leinster last month and have re-established their place in the top four at the expense of the Ospreys, but needed a last-gasp try from flanker James Eddie to escape
Ravenhill in September with a 13-12 win.
Townsend’s side have won five of their seven clashes with the Irish provinces this season.
