Garry Ringrose has been ruled out of Ireland's next two Six Nations matches against Wales and England after sustaining a broken finger in Saturday's 19-12 home win over Scotland.
Ringrose, replaced at halftime by Leinster team-mate Robbie Henshaw, was pictured following the contest with his left hand heavily strapped.
The IRFU confirmed that the Leinster centre underwent a 'procedure' on his hand and will be out of action until round four of the Six Nations when Ireland take on Italy at the Aviva Stadium.
Ringrose will remain with the Irish squad while he recovers.
Elsewhere Dave Kilcoyne and Caelan Doris are proceeding through the HIA process and will follow the graduated return to play protocols.
Tadgh Furlong will also be monitored after he reported some tightness in his calf muscle, following a full 80 minutes against the Scots.
