Irish heavyweights Munster and Leinster have revealed their starting lineups for the upcoming United Rugby Championship interprovincial derby at Thomond Park on St. Stephen's Day.

When the sides played in Dublin in October, Leinster ran out a comfortable winner, 27-13.

There are two changes to the Munster team that defeated the Northampton Saints last week. 

Shane Daly will start at fullback, with Calvin Nash and Keith Earls retaining their positions on the wings. Jack Crowley and Antoine Frisch will continue to play together in the midfield, with Conor Murray and Joey Carbery occupying the halfback positions.

In the front row, Dave Kilcoyne makes his first start since October and will join Niall Scannell and John Ryan, while Jean Kleyn and Tadhg Beirne will play in the second row. The starting lineup is rounded out by Jack O'Donoghue, captain Peter O'Mahony, and Gavin Coombes.

Josh Wycherley, Kiran McDonald and Patrick Campbell of the Greencore Munster Rugby Academy will be among the replacements. McDonald will make his first appearance since the team's win over South Africa A at P irc U¡ Chaoimh.

Unfortunately, several players are unavailable for selection due to injuries. 

The list includes Jeremy Loughman, who sustained a knock in training, plus Mike Haley and John Hodnett, who did not fully recover from last week's physical match against Northampton.

Leo Cullen has named a Leinster side that is particularly powerful in the backs, while a little lighter in terms of first-team players in the forwards.

Ten players who played in Leinster's win over Gloucester in the Heineken Champions Cup last week have been named in the starting lineup for the Thomond Park clash. 

Hugo Keenan will start at fullback, with Jordan Larmour and James Lowe on the wings.

Larmour, who returned from injury last week, will make his first start since early October. 

Captain Garry Ringrose will start at center, partnered by Jamie Osborne for the second time this season. Ross Byrne will start at fly-half, with Nick McCarthy making his first start of the season at scrum-half.

In the front row, Porter will be joined by Dan Sheehan and Cian Healy.

Ryan Baird and Joe McCarthy will form the second-row partnership for the first time together. The back row will consist of Rhys Ruddock, Scott Penny, and Max Deegan, with Ross Molony, Jack Conan, and Luke McGrath named as replacements.
