Five players sat out Ireland's first training session after the emotional roller-coaster of Wednesday's match.
Shay Given still has a slight hip problem, Gary Breen got a bang on his calf during the match, while Steve Finnan and Steve Staunton both have slight hamstring strains.
Matt Holland has a injured rib.
All are expected to be fit for Tuesday's make-or-break match with Saudi Arabia.
Jason McAteer participated in the light-hearted session, which included a Gaelic football match between the squad, and is on a course of anti-inflammatories for his troubled knee.
