The RDS hosts the top two teams in Conference A as Leinster, who will be without the suspended James Lowe after he was red carded against Munster, take on Ulster.

Leo Cullen's side are a mammoth 16 points clear at the top of the standings but Ulster will be looking to cement second spot with Benetton, Scarlets and Edinburgh hot on their heels.

That game kicks off at 5.15.
