Ireland internationals Rory Best and Craig Gilroy also return to the province's starting line-up following their involvement in the RBS 6 Nations.
With John Afoa in New Zealand for the birth of his third child, there is a first Ulster start for tighthead prop Ricky Lutton.
The 27-year-old Lutton, who was named Club Player of the Year at last year's Heineken Ulster Rugby Awards, signed a development contract with the province at the start of this season.

Callum Black and Peter Nelson retain their places among the replacements while Academy prop Kyle McCall, who has represented Ireland at Under-20 level, is in line to make his first senior appearance for Ulster off the bench.
