Ultan Dillane does not require surgery on his injured ankle and is winning his battle to be fit in time for the Six Nations.
The Kerryman has become a key part of Joe Schmidt's match-day 23 since making his debut in the Championship last season and had been expected to miss some of this year's tournament as a result of the injury.
However, news that he doesn't require an operation and is expected to be available in three or four weeks was part of a more positive injury bulletin from Connacht yesterday as the province confirmed Jack Carty's knee injury is not as serious as first feared.
However, Schmidt looks set to be without Leinster's Seán Cronin for the majority of Ireland's campaign as a result of the hamstring injury he suffered against Zebre last weekend. The hooker is expected to be ruled out for between eight and 12 weeks after undergoing scans on the tear.
