Ireland have received good news about the fitness of fly-half Johnny Sexton and back-row forward Sean O'Brien ahead of facing Argentina on Saturday.
Sexton was injured in the warm-up before last week's game against Fiji due to a tight groin and was removed as a precaution, but has been passed fit to face the Pumas in Dublin.
"At a stretch, Jonathan could have stayed in the squad on Saturday but it was felt it wasn't prudent and we withdrew him solely as a precaution," said Ireland team manager Michael Kearney.
"It's not even a minor concern to be honest. He received treatment over the weekend and even today there was considerable easing.
"The scan was nothing more than a precaution and it was determined there was no damage. Jonathan was back jogging and will train fully on Thursday and will be absolutely fine for Saturday."
Meanwhile, O'Brien came through his first training session of the season for Leinster after undergoing hip surgery. O'Brien will take part in team sessions next week before a decision is made regarding his selection.
