When Devin Toner takes to the RDS pitch tomorrow night the former Ireland second-row will equal Gordon D'Arcy's record as Leinster's most capped player.
he match against Ospreys will be the Meathman's 261st in a blue jersey and he'll hope to do enough to be in a position to break the record in Saturday week's final at the Ballsbridge venue against Munster.
Both Leo Cullen and Johann van Graan will have one eye on that fixture this weekend, but Cullen's team looks to have more players who will feature next week.
Harry Byrne continues at out-half as Ciaran Frawley resumes at No 12, while the in-form Scott Penny is at openside.
Munster, meanwhile, field three senior debuts to Cian Hurley, Diarmuid Barron and Paddy Patterson, while Andrew Conway is released from Ireland camp and starts on the wing against Benetton.
JJ Hanrahan is in the No 10 slot as Joey Carbery takes a break, while ex-Saracens full-back Matt Gallagher returns from a long injury absence and Tommy O'Donnell comes in from the wilderness to feature on the bench.
Ulster, meanwhile, have handed a first start to Offaly second-row Cormac Izuchukwu who has impressed off the bench in recent weeks as they close out their campaign at home to Zebre.
