Ulster lock Gary Longwell has been drafted into Ireland's 22-man squad for the RBS 6 Nations showdown with England at Twickenham on March 6.
Longwell made his last international appearance in the World Cup warm-up match against Italy last August and despite being named in Eddie O'Sullivan's squad for Australia, injury forced him to sit out the entire tournament.
He has taken the place of Munster lock Donncha O'Callaghan who limped off during the first half of Sunday's 36-15 victory over Wales after straining the medial ligament in his right knee.
O'Callaghan should recover in time for the clash with Italy at Lansdowne Road on March 20, but until then Paul O'Connell and Malcolm O'Kelly will form the second row with Longwell providing cover from the bench.
Otherwise, O'Sullivan has made no further changes to the side which humbled Wales in Dublin last weekend, with skipper Brian O'Driscoll on course to continue his midfield partnership with the in-form Gordon D'Arcy.
The team to face England will be announced next Tuesday.
As head coach Stuart Lancaster polishes the axe he will soon wield over his World Cup training squad, Exeter Chiefs coach Rob Baxter has backed Jack Nowell, Henry Slade and Luke Cowan-Dickie to be given a stay of execution.
Italy Under-20s held off a late Samoa blitz to retain their place in the World Rugby U20 Championship on Saturday and head coach Alessandro Troncon believes the experience will have served as a valuable lesson for his young troops.
