Les Kiss has named his match day squad for the crunch clash against Ospreys on Saturday as he looks to guide his side to the play-offs for a fourth successive year.
Craig Gilroy, a late withdrawal from the team last week, is reinstated to the starting XV, which is otherwise unchanged from the 30-6 win over Leinster.
Rory Best will again captain the side, with props Callum Black and Ricky Lutton, and second rows Pete Browne and Franco van der Merwe joining him in the front five. The back row trio of Iain Henderson, Chris Henry and Sean Reidy, which performed so effectively last week, is also retained.

Man of the Match in that game, Ruan Pienaar, will line out alongside Paddy Jackson at half back, with Stuart McCloskey and Luke Marshall continuing their midfield partnership. Gilroy, Andrew Trimble and Jared Payne complete the backline.
A bonus point win on Saturday would guarantee Ulster a play-off spot, and an outside chance of that game being at home. Anything less and they will be looking at other results to confirm their place in the last four, although fellow contenders Scarlets face a difficult trip away to Munster.
