Ross Byrne will make his Leinster comeback against Benetton tomorrow after recovering from an arm injury.
The Ireland out-half has been out of action since the end of November, when he suffered the injury against Munster.
His return for the top-of-the-table clash against the Italian side will also boost Ireland head coach Andy Farrell's options ahead of Saturday week’s Guinness Six Nations round three match against Wales.
The last of Byrne’s 22 caps came against Tonga at the World Cup. Ciaran Frawley, who had initially been released from Ireland camp, was recalled for international training.
Meanwhile, academy full-back Henry McErlean will make his Leinster debut in the BKT URC round ten match at the RDS tomorrow [3pm, live on RTÉ2 and RTÉ Player].
He was part of the Ireland team that won last year’s Under-20 Six Nations.
Tommy O’Brien and Rob Russell are named on the wings, with Liam Turner and a returning Jamie Osborne partnering each other in the centre.
For the first time this season, Byrne and Luke McGrath partner each other in the half-backs.
The duo have over a combined 350 Leinster caps.
In the pack, Jack Boyle and Thomas Clarkson pack down either side of Lee Barron in the front row. Ross Molony and Jason Jenkins are named in the second row.
Captain Scott Penny is joined in the back row by Will Connors and Max Deegan.
In the replacements, John McKee returns for the first time since sustaining an injury in the season opener against Glasgow Warriors, while Ben Brownlee is in line for his first appearance of the season.
Leinster: Henry McErlean; Tommy O'Brien, Liam Turner, Jamie Osborne, Rob Russell; Ross Byrne, Luke McGrath; Jack Boyle, Lee Barron, Thomas Clarkson; Ross Molony, Jason Jenkins; Will Connors, Scott Penny (capt), Max Deegan.
Replacements: John McKee, Ed Byrne, Michael Ala’alatoa, Brian Deeny, Rhys Ruddock, Ben Murphy, Sam Prendergast, Ben Brownlee.
Meanwhile, Connacht have made four changes from the side that saw off Bristol Bears in their last outing, with Dave Heffernan, Jack Aungier, Conor Oliver and the fit-again Cathal Forde [above] coming into the starting 15 for their trip to Cardiff [5.15pm, live on RTÉ2 and RTÉ Player].
Forde partners David Hawkshaw in the centre while the back three of full-back Tiernan O'Halloran and wingers Shayne Bolton and Andrew Smith is unchanged. Caolin Blade captains the side from scrum-half with JJ Hanrahan alongside him.
Denis Buckley plays alongside Heffernan and Aungier in the front row, while the second row of Niall Murray and Joe Joyce is unchanged.
The backrow sees Cian Prendergast move to the number 8 jersey, with Shamus Hurley-Langton going to blindside flanker and Oliver at openside.

Ulster are able to welcome back Ireland internationals Iain Henderson [above], Jacob Stockdale, Tom Stewart and Nick Timoney following their release from Six Nations camp.
The experienced front row sees Andrew Warwick start at loosehead, with John Andrew at hooker and Marty Moore starting at tighthead prop for their game away to Ospreys on Sunday [3pm].
In the second row, Harry Sheridan and skipper Henderson pair up as Ulster’s locks.
The back row sees David McCann start at blindside flanker. Marcus Rea starts at openside flanker, with Timoney starting at 8, as Ulster aim to win the battle at the breakdown in Swansea.
McFarland opts for the half-back pairing of Nathan Doak at scrum-half and Jake Flannery.
Stockdale returns from international camp to start on the left wing as he hopes to continue his try-scoring form, with the winger having dotted down six tries this season in the URC so far.
The centre partnership sees Jude Postlethwaite join James Hume.
Mike Lowry starts on the right wing, with Will Addison completing the backfield at full-back.
Ulster can call on a wealth of talent and experience from the bench, with a 5:3 split that features Stewart and Springbok prop Steven Kitshoff.
