Ireland have been boosted by the news that Jonathan Sexton and Jamie Heaslip are both fit to face Wales in Saturday's Six Nations clash in Cardiff.
Fly-half Sexton was a fitness concern after struggling with a hamstring injury, but the Racing Metro man took part in training on Tuesday.
Number eight Heaslip was named in Ireland's 36-man squad for the final two rounds of the competition on Monday.
It was initially thought that Heaslip would miss the rest of the tournament after he suffered three fractured vertebrae when he was kneed by France's Pascal Pape in Ireland's second match.
However, assistant coach Richie Murphy confirmed the duo would be available at the Millennium Stadium, as will Sean O'Brien and Jared Payne - who have recovered from concussion.
"Johnny took full part in training this morning, he has done all the team stuff and trained well," Murphy said on Tuesday.
"Everyone else has come through, Jamie trained Monday and Tuesday so he's fit and healthy and ready to go.
"And the two boys, Jared and Sean O'Brien both passed their return to play protocols.
"They have done contact today so as long as there's no reaction over the next 24 hours they are both fit and ready to go
"It looks like a full deck to pick from, and everyone is very upbeat, everyone enjoyed that session this morning, the intensity was right up there."
Defending champions Ireland defeated England 19-9 last time out and remain on course for the Grand Slam.
