Jimmy O'Brien will be assessed by the Leinster medical team ahead of his side's Guinness PRO14 clash against Scarlets.
O'Brien scored a try in the opening half of Leinster's defeat of Cardiff on Sunday but he was forced off at the interval after sustaining a back injury.
The medical team will assess the injury before making a call on his involvement in Sunday's game in Wales, which is live on eir sport.
Rory O'Loughlin missed the win over Cardiff after failing to make sufficient progress in his recovery from a should injury and he will have to prove his fitness to the medical team if he is to feature at the weekend.
Leinster have a lengthy injury list with Tadhg Furlong (calf), Ciarán Parker (thumb), Tommy O’Brien (ankle), Jack Conan (neck), Garry Ringrose (jaw), Max Deegan (knee), Jordan Larmour (shoulder), Vakh Abdaladze (back) and Adam Byrne (hamstring) all sidelined, but Conor O’Brien has returned to training and could feature over the coming weeks.
Leinster's Guinness PRO14 clash with Scarlets is live on eir sport 1 on Sunday, 29 November (KO 5.15pm).
