Ireland boss Giovanni Trapattoni has received a series of fitness boosts ahead of Saturday's Euro 2012 warm-up game against Bosnia.
Skipper Robbie Keane trained fully at Gannon Park in Malahide 24 hours after his arrival from Los Angeles to confirm his recovery from a hamstring strain.
He was joined by Shane Long, Jon Walters and Keith Andrews, who did not complete the morning session with minor niggles.
Keith Fahey, who has been nursing a groin problem, is progressing and is expected to be fit for the weekend, while a decision on Kevin Foley (hamstring) will be taken later in the week.
Keeper Shay Given, who had a scan on a knee injury on Monday, will not train on Wednesday, nor will defender Richard Dunne, who has a micro-tear in his lower abdominal wall.
John O'Shea, who has been all but ruled out of the Bosnia game, is unlikely to train, but like Dunne, is expected to be fit for the finals.
Given was sent for a scan on a knee injury he picked up in training on Monday, and a Football Association of Ireland spokesman confirmed: "After undergoing a scan, it was concluded that Shay should sit out training for the next two to three days for precautionary measures.''
Trapattoni later suggested the 36-year-old Aston Villa keeper is his biggest concern ahead of Euro 2012 - which for the Republic kicks off against Croatia on June 10 - and hinted that either Sunderland's Keiren Westwood or David Forde of Millwall could play in Saturday's friendly against Bosnia.
He said: "There is only Shay Given, who has a little bit of a problem. We have to decide run the risk or stay. We have another two [keepers].
"For this game, we will decide with the doctor because at this moment, we don't need to run the risk."
