Jeremy Loughman has been called into the Irish squad for the first time.
The Munster prop is drafted in ahead of this weekend's Six Nations clash with England.
He will provide cover in the absence of Andrew Porter, who has been ruled out of the remainder of the competition due to an ankle injury.
Jordan Larmour has also joined the injured list, after picking up a hip problem in Leinster's win over Benetton last weekend.
Eight players return to the squad after provincial action, including Ulster's Iain Henderson.
He played 80 minutes in their URC win over Cardiff and could come into contention for game time with Ireland in the coming weeks.
The squad reassembled at Carton House last night ahead of this weekend's clash in Twickenham.
