Ireland prop Cian Healy is striving to show he is ready to take his place in their squad for the Rugby World Cup.
Cian Healy is being monitored on an hourly basis as the Ireland prop battles to prove he is fit enough to play in the Rugby World Cup.
The Leinster loosehead underwent neck surgery in May and faces a race against time to secure a place in Ireland's 31-man squad for the tournament in England and Wales, which starts next month.
Six Nations champions Ireland face Wales in Dublin on Saturday and defence coach Les Kiss has given an update on Healy, with the World Cup squad due to be named on Monday.
"It's an hourly thing. Each hour we get an update on it and we'll see how that stands on Sunday night. We've got people working on the rehab things, said Kiss.
"Cian is gradually being exposed to more and more rugby. I'm not sure if we'd be able to say that's a chance of playing [against Wales].
"He did a lot in the session today. I did some personal work with him at the end of the session around the contact area so some positive results coming through there.
"He will be assessed by the medics again at the end of the session. He did more in the session today which is promising but we need to get it from the medics."
Andrew Trimble (foot) is set to face Wales, but whether Marty Moore (foot) is able to feature remains to be seen.
"Trimby has come up really good. He trained fully so he's fit to go. We know what Trimby has delivered in the past, so he's going to play and we'll know. That's the bottom line." added Kiss.
"Marty is in a boot still. It's there to protect the joint. He'll train on Thursday and that will give him and us a good idea of where he is and that should be able to prove whether he is available on the weekend and that's probably his important session."
