Leinster No 8 Caelan Doris and Ulster utility back Will Addison will join 21 of the 23 players that featured for Ireland against Wales last weekend when Andy Farrell hosts a two-day camp in Cork later this week.
Hooker Rónan Kelleher and back-row Max Deegan, who both came off the bench at the Aviva Stadium last Saturday, are among 13 players released to their provinces for PRO14 game-time.
Doris missed the win as a result of the head injury that prematurely ended his debut against Scotland in round one and now faces a battle to get back into the team after Peter O'Mahony and CJ Stander's strong showings against Wales.
Addison has not been available for selection for the first two games, but with Robbie Henshaw recovering from a head injury he may see some action at training in the Cork Institute of Technology this week.
Otherwise, Farrell looks set to stick closely to the core of his unbeaten team for his first away game as the head coach prepares to face off against his old team, captained by his son Owen.
As well as Deegan and Kelleher, Leinster will welcome Will Connors, Dave Kearney and Luke McGrath back for their match against Cheetahs, while Munster have Chris Farrell and Jack O'Donoghue for their clash with Southern Kings.
Connacht can call on Ultan Dillane and Dave Heffernan against Cardiff Blues, while Billy Burns, Stuart McCloskey, Jack McGrath and Tom O'Toole are available for Ulster against Ospreys.
ANDREW Conway says that Ireland will not be getting swept away with title talk as his side bid to cast aside of two successive tournament flops by winning a Triple Crown in Twickenham later this month.
What a difference a week makes. After the Scottish game, certain sectors of the media were writing Ireland off, saying that they had little chance against a confident Welsh side, defending last year’s Grand Slam title and fresh from a comprehensive win, albeit against a less-than-convincing Italian side.
If the last two weeks have taught us anything, particularly the win over Wales, it is that small tweaks and picking form players in an already established game-plan, can make a big difference.
