Cullen is also able to call upon the services of five players released from the Irish Rugby World Cup training squad in Michael Bent, Jack Conan, Fergus McFadden, Noel Reid and Isaac Boss.
The front row consists of Michael Bent, Aaron Dundon at hooker and Jamie Hagan at tighthead, with Tom Denton and Mike McCarthy locking down behind to complete the tight five.
Kevin McLaughlin captains the side from blindside flanker for his 115th appearance in blue after an injury disrupted season last year where he only played five times. His last competitive appearance was against Connacht in December.
Dan Leavy makes his first start for the province from openside. The UCD man made three appearances last season off the bench while still in the Leinster Academy. Jack Conan completes the pack from number 8.
Luke McGrath and Cathal Marsh get another opportunity to shine having started both pre-season games at nine and ten. Marsh will also be making his first start for Leinster. His only previous appearance coming off the bench against Zebre in April 2013.
Last years joint top try scorer Darragh Fanning starts on the left wing, with Fergus McFadden on the right, while Noel Reid and Ben Te'o start in the centre.
On the replacements bench one of Royce Burke-Flynn, Ross Byrne or Garry Ringrose will become Leinster player number 1235 if they make an appearance off the bench as all three are in line to make their debut in Meggetland.
Burke-Flynn was signed from Clontarf during pre-season having previously been a part of the Leinster Academy, while Byrne and Ringrose are both still members of the Leinster Academy.
The game kicks off at 7.35pm tomorrow evening on TG4 and updates will be provided on the Leinster Rugby twitter account.
