This is a welcome and timely return following a long road back from injury. Brian O'Driscoll and Shane Horgan are rested.
Ulster have also named their squad. Lock's Ryan Caldwell and Carlo Del Fava are both ruled out with injuries. As are former Leinster scrum half Cillian Willis and Scottish International Simon Danielli.
Connacht will name their team after training on St. Stephen's Day while Munster coach Tony McGahan has named a strong squad for the trip to the Sportsground.
Both games are sold out.
