John O'Shea took a full part in today's Republic of Ireland training session and should now play in Slovakia on Saturday.
The versatile Manchester United clubman shipped a knock to a knee during yesterday's session and retired to the sidelines with ice-pack in hand.
The Irish medical team monitored the Waterford man's situation overnight and gave him the all-clear to resume his preparations ahead of Saturday's crunch European qualifier.
With Steve Finnan and Stephen Carr ruled out of the weekend game, O'Shea's availability is paramount for a defence that also harbours slight concerns over Paul McShane.
The Sunderland defender came through a light workout this morning and will be available for selection even if that means receiving a pain-killing injection in his shoulder to play.
Manager Steve Staunton is receiving daily bulletins from Liverpool and Wolves over the fitness of Steve Finnan and Darren Potter respectively.
Finnan was ruled out last night having sustained a knee injury in his club's demolition of Derby at the weekend while Potter was deemed unavailable earlier this week owing to a groin strain.
Staunton, though, is keeping his fingers crossed that both players can join the squad in Prague next week ahead of Wednesday's qualifier against the Czech Republic.
Don Givens, meanwhile, has named his starting team for the Republic of Ireland's European under-21 qualifier against Portugal tomorrow night.
Celtic defender Darren O'Dea will captain the side as Givens' men launch their campaign against the group favourites at Turner's Cross.
Cork-born duo Stephen O'Halloran of Aston Villa and Ipswich's Billy Clarke both start in their hometown city. Clarke will be joined up front by Stoke's Adam Rooney and James O'Brien of Celtic.
The midfield trio of Wolves' Stephen Gleeson, Patrick Cregg of Falkirk and Sheffield United's Stephen Quinn will play behind them.
O'Halloran and O'Dea will play in defence, alongside Richard Keogh of Bristol City and Blackburn's Eddie Nolan, while Darren Randolph of Charlton starts between the posts.
"If we were to finish in the top two in this group it would be a tremendous achievement but we can't afford to drop our standards if we're to get a result," said Givens who saw his side secure a 2-2 friendly draw in Germany a fortnight ago.
"Our performances in our last two games against the Germans and Holland were very encouraging and that's the level we'll need to reach again.
"We've watched tapes of Portugal's last game against the Maltese and it was all one-way traffic but we know them well having played against them (losing 1-0) in the Madeira Tournament in March.
"At this level it is about our own performances. We need to make sure we are at our best in terms of technique, tactics, discipline and concentration."
Ireland also have England, Bulgaria and Montenegro in their group as they bid to reach next year's finals in Sweden.
A limited number of tickets for the match are available through Ticketmaster outlets. Supporters can also buy tickets outside the stadium prior to kick-off. Tickets cost €25 for adults and €10 for children.
