Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Development hooker Niall Annett, who made a significant impact off the bench during last Saturday's derby defeat to Munster, has also been included despite Rory Best returning to the squad.
Best is one of a number of international players, including Andrew Trimble, Iain Henderson and Ruan Pienaar, who are available after missing the league trip to Thomond Park.
