Robbie Henshaw has emerged as an injury doubt for Ireland's Rugby World Cup clash with Scotland on Saturday.
The 30-year-old Leinster centre, who started on the bench in the wins over South Africa and Tonga, missed the opening-round victory over Romania after pulling up in the captain's run with a hamstring issue.
"Robbie has a bit of a niggle and we're finding out about that today," forwards coach Paul O'Connell told reporters this morning.
"I'm sure there'll be some information on that tomorrow."
If Henshaw misses out, it could open the door for one of Jimmy O'Brien or Stuart McCloskey to make their first appearances of the tournament from the bench, while Keith Earls is also a versatile option to have in the 23 shirt.
The rest of the 33-man panel came through the training session ahead of the final Pool B game, with James Ryan on course to be available after suffering a bang on his hand in the win against the Springboks.
The Irish coaching team are unlikely to make any drastic changes to the staring XV, although Dan Sheehan could come in to make his first start of the World Cup, having returned from injury against South Africa.
Ireland will guarantee qualification for the knock-out stages if they beat or draw with Scotland.
The world number one side have won all three pool games to bring their streak up to 16 matches, but with such high stakes this week O'Connell knows they will need to find extra gears at Stade de France on Saturday.
"That's it, we just have to get better," he added.
"I think that's one of the things the lads are really good at, they're really good at staying focused on the next game and not looking beyond it.
"They kind of acknowledge, you know, whenever we've been on tour down in New Zealand or whenever we're playing in the Six Nations, in terms of having a chance of winning it, they acknowledge it, they might have a quick chat about it, and that allows them to focus on what's in front of them.
"Staying focused on this game and absolutely nothing else is a skillset they've gotten really good at. Then we've just got to get better.
"There's a lot of things that we were excellent at against South Africa but there's a lot of things we can improve on in terms of our attack, in terms of our defence, in terms of ruck, lineout obviously. So there's always bits to get better at and that's what I think sometimes helps the lads kind of tune out the noise a little bit of what might happen after the game.
"They enjoy focusing on the bits and pieces that help them be better and they can ignore the bigger picture of the game at the weekend."
