Changes have also been rung in the three-quarters where Matthew Watkins moves to the bench to make way for Aisea Havili. The Tongan international starts on the left wing, with former British Lion Dafydd James moving to outside centre and Tal Selley switching from the left to the right flank.
A finger injury to Wales flanker Dafydd Jones in the Edinburgh defeat forces Jenkins into a third change in the forwards with Jonathan Mills joining Gavin Thomas and Alix Popham in the back row. Former Bath man Mills will be hoping to impress with Jones likely to be out for up to three months following surgery leaving the number six jersey up for grabs.
Dave Duley and Chris McDonald are given places on the bench as the 2003 Celtic champions seek an immediate return to form.
