Squad news: The rest of Ireland's Grand Slam winners may have been afforded a period of rest and recuperation, but Gordon D'Arcy will return to domestic action straight away after being named in the Leinster squad for Sunday's match against Ulster.

D’Arcy, who started the last two Six Nations matches and played the entire 80 minutes against Wales, is joined in Michael Cheika’s 27-man panel by the returning fit-again Leo Cullen and CJ van der Linde.

Leinster captain Cullen is in line to make his first appearance since January having recovered from the shoulder injury sustained in the Heineken Cup against Wasps while van der Linde dislocated a toe in that same match.

Malcolm O’Kelly, Shane Jennings, Girvan Dempsey and Shane Horgan –used sparingly if at all by Declan Kidney – are also included for the match at the RDS.

Ulster have yet to name their squad but are unlikely to call upon Rory Best, Tom Court or Paddy Wallace while Stephen Ferris is definitely ruled out with a dislocated finger.

Magners, meanwhile, has extended its sponsorship of the Celtic League for another two years. The new deal will run until the end of the 2010-11 season.
