Munster have named Craig Casey and Dave Kilcoyne in their team to play Edinburgh in the United Rugby Championship tomorrow night.
The pair were released from Ireland's Six Nations training camp earlier this week and are in line for game time at Thomond Park having not featured in the match-day squads against Wales or France.
Prop Kilcoyne will become just the 12th Munster player to reach the 200-cap landmark for the province.
He is one of four changes to the starting XV that lost to Glasgow last week as the returning international scrums down with Diarmuid Barron and Stephen Archer in the front row for the 7.35pm kick-off.
The remaining pack is unchanged with Jean Kleyn and Fineen Wycherley in the second row and captain Jack O’Donoghue, Chris Cloete and Coombes, who is also part of Andy Farrell’s extended panel, across the back row.
The backline sees the introduction of Casey, Dan Goggin, and Calvin Nash with the scrum-half linking up with Ben Healy in the half backs as Goggin joins Chris Farrell in midfield.
Mike Haley starts at full-back with Simon Zebo on the wing and Nash coming in on the other flank.
Niall Scannell returns from shoulder injury to be named in the replacements.
Munster: Mike Haley; Calvin Nash, Chris Farrell, Dan Goggin, Simon Zebo; Ben Healy, Craig Casey; Dave Kilcoyne, Diarmuid Barron, Stephen Archer; Jean Kleyn, Fineen Wycherley; Jack O’Donoghue, Chris Cloete, Gavin Coombes.
Replacements: Niall Scannell, Jeremy Loughman, John Ryan, Alex Kendellen, John Hodnett, Neil Cronin, Jack Crowley, Shane Daly.
Edinburgh have four Scotland internationals back in their team.
Centre Mark Bennett, stand-off Blair Kinghorn, scrum-half Ben Vellacott and back-row Nick Haining all come back in as Mike Blair makes four changes.
Head coach Blair said: "It's great we’re able to welcome back some of our Scotland guys back into the squad. They bring added strength to a group that did some good things against Leinster last time out.
"While it’s great to have experienced internationalists back involved, this period is also brilliant for our younger players.
"They can show what they can do and see what it takes to win at this level. This is excellent for their development, while at the same time, we are able to put out a team that is capable of winning these games."
Blair, whose team lost 26-7 to Leinster last weekend, added: "We are expecting a real battle out there. Part of the disappointment of the Leinster game was around our physicality.
"There is no better place to go than Thomond Park to see if we have learned the lessons from the week before. We can’t wait for the challenge."
Bennett will captain Edinburgh for the first time while Kinghorn replaces Jaco van der Walt, who is listed among the unavailable players.
