Johnny Sexton remains sidelined for Leinster's Pro14 Rainbow Cup clash against Ulster at the RDS on Friday night.
The Ireland out-half hasn't played since suffering a head injury in Leinster's Heineken Champions Cup quarter-final win over Exeter in April. It was his third head injury since February.
Last Thursday he was omitted from the Lions squad for the summer tour to South Africa, with head coach Warren Gatland explaining: "He's been rested on a number of occasions, and unfortunately that's possibly what swayed it for us in terms of us not having the confidence that he can get through what's going to be a tough, physical tour."
Rhys Ruddock (calf), Harry Byrne (hamstring), Will Connors (knee), Jack Dunne (ankle), Adam Byrne (quad), Dan Leavy (knee), Conor O'Brien (knee) and Max Deegan (knee) all still on the injured list. Ciarán Frawley hurt his shoulder and his hamstring in the win against Connacht last Saturday and is also unavailable.
In more positive news Caelan Doris is due to return to full training this week after getting over a minor calf issue while versatile back Jimmy O'Brien has recovered from his hamstring injury.
Jamison Gibson-Park's hamstrng will be further assessed as the week progresses while Jack Conan, who went off for a HIA against Connacht, follows return to play protocols.
