Leinster are without James Lowe and Johnny Sexton for their Aviva Stadium clash with Ulster this Saturday.
Head coach Leo Cullen has named a back-three of Jordan Larmour, Dave Kearney and Adam Byrne meaning Rob Kearney has to settle for a place on the bench.
Johnny Sexton is also unavailable due to injury so Ross Byrne starts at out-half.
Dan Leavy's return to full fitness sees him slot in on the bench while Ed Byrne's inclusion means there is no space for Jack McGrath in the matchday squad.

The Saturday evening tie is the only All-Irish clash of the four quarter-finals. Leinster are without Robbie Henshaw and Devin Toner due to injury. James Lowe cannot be included due to the 'overseas players' limit as Scott Fardy and Jamison Gibson-Park occupy those two spots.
On the bench, Mick Kearney is in line to play his 50th game for the province for what might also be his first game in the Champions Cup this season.
Andrew Porter is also in line to win his 50th cap from the bench.
