Brian O'Driscoll is expected to be fit to face Scotland on Sunday.
Ireland were finally offered some respite from their injury crisis with the expectation that Brian O’Driscoll and Sean O’Brien will be fit to face Scotland.
The Leinster pair sustained ankle and hamstring injuries in the 12-6 RBS 6 Nations defeat by England, but have returned to full training and should participate at Murrayfield on Sunday.
Uncapped Ulster centre Luke Marshall is available to replace the injured Gordon D’Arcy after recovering from the dead leg incurred on provincial duty on Friday night.
However, the prognosis over Donnacha Ryan is less clear cut after the Munster lock, who is nursing a back spasm, took only a limited part in training.
“Brian and Sean trained this morning and are expected to be fully involved for the rest of the week,” said team manager Mick Kearney.
“Donnacha continues to recover from a back spasm. He took part in some of the session today and we’re continuing to monitor his rehab.
“Luke Marshall has recovered really well from his dead leg and trained fully this morning. There are no concerns about him.”
Head coach Declan Kidney names his team at lunchtime on Wednesday.
