Rugby Team News: CJ Van Der Linde and Rocky Elsom will both make their Leinster debuts when they take on provincial rivals Munster in Sunday's Magners League sell-out at the RDS in Dublin.

Skipper Leo Cullen partners Malcolm O'Kelly in the second row with Elsom lining up in the back row alongside Shane Jennings and Jamie Heaslip.

In the backline, Chris Whitaker partners Jonathan Sexton in the half-backs with Shane Horgan starting on the right wing, Luke Fitzgerald on the left and Girvan Dempsey at full-back.

Munster coach Tony McGahan makes five changes from the side that started against Cardiff Blues last time out for Sunday's provincial showdown.

Keith Earls takes over from Denis Hurley at full-back with the other change in the backline seeing Tomas O'Leary preferred to start ahead of Peter Stringer who is named on the bench.

Up front Marcus Horan returns to the front row in place of Tony Buckley, Donncha O'Callaghan partners his captain Paul O'Connell in the second row and the experienced David Wallace takes the number seven jersey from Niall Ronan whose two tries last weekend helped Munster to a bonus point win.

Supporters are encouraged to use public transport on Sunday as there will be no parking at the RDS because there are other events taking place at the venue.

Ulster coach Matt Williams has also named his starting XV as they go in search of their first league win away to the Ospreys at Liberty Stadium on Saturday.

Williams has opted for an experienced line up that shows a number of changes to the side defeated by the Dragons at Ravenhill.

Rory Best remains the biggest loss after receiving a knock to the knee in last Friday's game. As a precaution he is rested in anticipation of Ulster's opening Heineken Cup match against Stade Francais at home in two week's time.

Italian Carlo Del Fava picks up the captain's armband in Best's absence while Nigel Brady steps into replace Best as hooker. Bryn Cunningham replaces Clinton Schifcofske at full-back, with Schifcofske moving out to the wing. Andrew Trimble moves into the centre to partner Rob Dewey, which means Darren Cave drops out of the squad.

Justin Fitzpatrick replaces Tom Court in the starting XV. Joining Court on the bench is the returning Stephen Ferris. He has been out of action all season recovering from a back injury picked up during Ireland's summer tour.
