CIAN HEALY AND JIMMY O' BRIEN could miss next Sunday's Heineken Champions Cup semi-final against Toulouse.
The pair left the field against Leicester on Saturday with head injury assessments in the 23-14 victory over the English side.
Andrew Porter came off for Healy, but a HIA happened five minutes before the end.
While O'Brien was replaced by Tommy O'Brien in the 71st minute.
If they are to make the game for Sunday, they will have to follow return-to-play protocols, say Leinster.
The game also saw the return of James Ryan and Rónan Kelleher.
Both have been ruled out since the Six Nations, while Max Deegan could be an option for the back row this weekend.
