Josh van der Flier and Garry Ringrose have overcome injuries to take their place in the Leinster team for Saturday's BKT URC final against Bulls.
However, the game comes too soon for fellow British and Irish Lions duo Tadhg Furlong and Hugo Keenan, who miss out on the Croke Park showdown (Saturday 5pm) with calf issues.
Ireland flanker Van der Flier suffered a hamstring injury in the quarter-final against Scarlets, while centre Ringrose has recovered from a calf injury.
They are the only changes to the side that beat Glasgow in the semi-final.
Joe McCarthy and James Ryan continue their partnership in the second row with Andrew Porter and Thomas Clarkson packing down either side of hooker Dan Sheehan.
Ringrose partners Jordie Barrett in the centre, with Jamison Gibson-Park and Sam Prendergast the half-backs.
Tommy O’Brien and James Lowe continue on the wings with Jimmy O’Brien named at full-back once more.
Rónan Kelleher, Jack Boyle and Rabah Slimani provide the front row reinforcements with RG Snyman and Max Deegan offering cover from the bench.
Jamie Osborne moves to the replacements alongside Luke McGrath and the departing Ross Byrne, who is set to make his 186th and final appearance for Leinster.
Meanwhile, Bulls coach Jake White has made one change to the team that beat the Sharks last weekend.
Marco van Staden comes into replace injured back row Cameron Hanekom, with Marcell Coetzee moving to number 8.
