Captain Leo Cullen and prop CJ van der Linde are not included in the Leinster squad to play Edinburgh in Sunday's Heineken Cup Pool 2 clash at the RDS (KO: 1pm).
It is a blow to coach Michael Cheika's plan to outmuscle the Scots, however front rowers Stan Wright and Bernard Jackman should be involved.
Malcolm O'Kelly will have to wait until Thursday evening to find out if he has escaped sanction for an alleged kick to the head of Phil Vickery against London Wasps last Saturday.
Almost 16,000 tickets have now been sold for Leinster's final Heineken Cup pool clash against Edinburgh.
The team is expected to be named on Friday lunchtime.
