Robbie Henshaw and Tadhg Furlong will both start for Leinster in their United Rugby Championship meeting with Ulster tomorrow.
Ulster, meanwhile, have been able to recall John Cooney to their starting team.
He's been out with a hamstring problem since their opening game of the season.
Furlong's starting role for Leinster may come as a surprise, given his prominence for Ireland during a busy Autumn Nations Series schedule.
However, the Wexford native will line out in the front row, fresh from the contract extension he signed during the week.
Henshaw's start comes following a period hampered by injury, though he made his return last week against Argentina.
He'll team up in the centre alongside Ciaran Frawley.
Leo Cullen also hands a first start of the campaign to James Tracy.
Vakh Abdaladze and Will Connors are both named on the bench could make first appearances of the season if introduced.
Ulster's Tom Stewart could make his debut from the bench if called upon by Dan McFarland.
They come into the game off the back of a hefty defeat to Connacht at the Aviva Stadium, while Leinster are five from five.
Kick-off at the RDS is at 8pm.
