British & Irish Lions flanker Iain Henderson will captain Ulster for the first time as Les Kiss names a starting XV that features 12 internationals.
Kiss has made three personnel changes from their win over Connacht in the PRO14, with Henderson shifting to the second row while Robbie Diack and Sean Reidy come in at blindside and openside respectively. In the backline, Louis Ludik earns selection on the right wing while Christain Lealiifano will make his European debut from fly-half. Rory Best remains out injured.
Wasps are bolstered by the return of captain Joe Launchbury as well as England back row Nathan Hughes and fly-half Jimmy Gopperth. Christain Wade has been recalled on the right wing as has Dan Robson at scrum-half.
England’s Elliot Daly and James Haskell also start, while Springboks star Willie le Roux will wear the No. 15 jersey.
