Jordan Larmour is a welcome return to the Leinster team for tomorrow night's crucial PRO14 visit of Ulster to the RDS.
The Irish international returns to the wing following a three month injury layoff, while Johnny Sexton has been passed fit to play after his early departure against Connacht due to a head injury.
Sexton and Dave Kearney are the only survivors in the starting team from last week's defeat, with Jamison Gibson Park coming in at scrum half.
Ross Byrne also starts, but in an unfamiliar role at outside centre, playing alongside Robbie Henshaw in midfield. Jordan Larmour is joined in the back three by Dave Kearney and Hugo Keenan who was rested a week ago.
Sean Cronin will pack down at hooker, with Cian Healy and Andrew Porter either side of him, while James Ryan is back in the second row alongside Scott Fardy.
The fully-changed pack is completed with Rhys Ruddock and Josh van der Flier on the flanks, and Caelan Doris at number 8.
Following Leinster's defeat last Saturday versus Connacht - as well as Ulster's victory over Munster - Leo Cullen's side trail Ulster by eight points at the top of the conference, although they have two games in hand.
A first away win against Leinster since 2013 would put their destiny firmly in their own hands with five rounds of the regular season to play, but they come into the match with a number of high profile players unavailable due to injury - namely Jacob Stockdale, Sean Reidy, Jack McGrath and Iain Henderson.
Stockdale's place is taken by Michael Lowry at full back; one of six changes from last week's victory against Munster.
The rest of the backline remains in place, with five changes in the pack.
Andy Warwick starts in place of Eric O'Sullivan at loosehead, Alan O'Connor returns as Kieran Treadwell goes to the bench, while it's an all-new back-row of Greg Jones, Jordi Murphy and Marcell Coetzee
