The IRFU has confirmed Rob Kearney is suffering from tightness in his calf and is an injury worry ahead of the opening World Cup match against Scotland in Yokohama.
The squad is not training today but it's hoped Kearney will be able to run on Wednesday and he's not yet being ruled out of Sunday's clash.
Robbie Henshaw continues his rehabilitation from a hamstring strain.
The IRFU say there are no other injury concerns at the moment and everyone else is good to go.
Strength and conditioning coach Ciaran Ruddock says they're not concerned about the nature of the injuries the players have been picking up.
Speaking to the press, he said: "You never want to see anyone getting injured when you're coaching. There is not a huge concern at the moment.
"We've put together a really good plan and even if you look at the players that are fit and healthy coming into this tournament, we're confident that we have periodised it very well to allow the guys to be performing at their best."
'We have put together a really plan,' says Ireland’s Strength and Conditioning coach Ciarán Ruddock
