Garry Ringrose and James Lowe are set to return to Leinster training but are unlikely to be involved against Munster in Saturday's rearranged Guinness PRO14 clash at Thomond Park (7.35pm).
Ringrose (jaw) and Lowe (groin) will be further assessed but may not be risked by Leo Cullen for the big interpro clash.
Winger Lowe hasn't played since injuring his groin in training after Ireland's Autumn Nations Cup loss to England in November.
Ringrose did return from the fractured jaw he suffered in the Six Nations against Italy in October, but the centre - Leinster's player of the year last season - suffered another jaw injury against Northampton Saints at the RDS in the Champions Cup last month.
The Blues are boosted by the news that Sean Cronin has recovered from a knee injury sustained against Ulster and is expected to train as normal, as is Ciaran Frawley, who is back after a hamstring injury.
Tadhg Furlong, Rory O'Loughlin and Scott Penny are among those who won't return to action this week.
