Ryan back for Leinster as Nankivell returns for Munster published at 12:48 11 October
James Ryan returns to the Leinster side to partner former Munster player RG Snyman in the second row for Saturday's sold-out interprovincial United Rugby Championship game at Croke Park (17:45 BST).
Ryan's inclusion is one of three changes from the team which started last weekend's 35-5 win over Benetton in Italy.
Liam Turner is selected on the wing, replacing the injured Jimmy O'Brien, and hooker Lee Barron comes in at hooker.
Munster make four personnel changes and one positional switch after securing a bonus-point win over Ospreys last week.
Fit-again centre Alex Nankivell returns from a shoulder injury after missing his side's last two games.
Sean O'Brien starts on the wing after returning from Emerging Ireland's tour to South Africa.
Prop Stephen Archer makes his first start of the season in place of injured tight-head Oli Jager, with Gavin Coombes returning to the starting XV at number eight and Jack O'Donoghue moving to blindside flanker in the absence of the injured Peter O'Mahony.
Mike Haley is fit to start at full-back while Tom Ahern is named among the replacements after recovering from an ankle injury suffered against Ulster in June.
Three academy players are included among the Munster replacements - prop Kieran Ryan, flanker Ruadhán Quinn and winger Shay McCarthy.
Leinster are top of the URC table after winning their opening three games while third-placed Munster are four points behind.
The match will be played in front of a sold-out crowd of 82,000 at the home of gaelic games in Ireland as Leinster's RDS home is being redeveloped.
