Joey Carbery suffered an ankle injury scare as Ireland eased past Italy 29-10 in their first World Cup warm-up match in Dublin.
Fly-half Carbery will face an anxious wait to discover whether the new knee concern will dent his World Cup hopes.
Premier playmaker Johnny Sexton is expected to be fit shortly following a thumb strain, but Ireland can ill afford to lose either of their main backline pivots.
Connacht’s Jack Carty and Leinster’s Ross Byrne would be the men to understudy British and Irish Lions fly-half Sexton in Japan, should Carbery miss out through injury.
New Zealand-born Carbery offers Ireland added selection flexibility though, with the ability to cover full-back, and even centre at a push.
Carbery, Dave Kearney, Andrew Conway, Jordi Murphy and Kieran Marmion all crossed as an experimental Ireland line-up secured a routine Aviva Stadium victory.
Chris Farrell increased his chances of World Cup travel with a smart showing at inside centre, but beyond that Ireland’s coaching team were not handed many new selection headaches.
Ireland were sloppy from the start, a curious Carbery crossfield bomb from his own 22 an unusual – and unsuccessful – exit strategy.
Dave Kearney then botched a nailed-on try, knocking on at the whitewash when attempting to scoop up Carbery’s hack through.
Italy struck first then, converting a driven lineout when the aggressive Mbanda dived home.
But just when Ireland expected to pull away, the Italians inflicted another flesh wound.
Giulio Bisegni’s cute grubber kick caught out Jordan Larmour in Ireland’s backfield, and Carlo Canna reached the bouncing ball first, to double the visitors’ try count.
Finally Ireland approached something resembling a rhythm, stringing the phases together deep in Azzurri territory.
Dave Kearney made amends for his early howler with a neat finish in the left corner, that owed everything to Garry Ringrose’s pass out of the tackle. It enabled Larmour to fire out wide, and Kearney junior did the rest.
Andrew Conway walked in a third at the death of the half, to leave Ireland leading 19-10 at the interval.
Number eight Jordi Murphy capped a driven lineout for Ireland’s fourth try, in a solid second-half opening.
Both sides meandered through an utterly-forgettable third quarter, save for that worrying injury to Carbery.
Replacement scrum-half Marmion charged down Test debutant and Italy counterpart Callum Braley to claim the hosts’ fifth score.
