The FAI say Shay Given's visit to a London doctor is precautionary.

Ireland keeper Shay Given will travel to London to consult a specialist over his knee injury.

The 36-year-old, who has missed training for the last two days after sustaining the problem, will return to Ireland’s Portmarnock base the same day with the camp insisting the visit to a doctor he has used before is purely precautionary.

An FAI spokesman said: “Shay Given will travel to London tomorrow to visit a knee specialist that he has seen in the past. He will return to Portmarnock in the evening.

“This is purely precautionary and Shay remains fine for the Euros.”

Given left training early on Monday morning and although there was no major concern over his injury, the decision to rest him for two or three days was taken as a precaution.

Manager Giovanni Trapattoni remains confident the Aston Villa goalkeeper will be fit for the Euro 2012 finals, but had already all but ruled him out of Saturday’s friendly against Bosnia-Herzegovina.

The news came less than an hour after the Italian had drafted Paul McShane into the squad as defensive cover with Richard Dunne, John O’Shea, Sean St Ledger and Kevin Foley all struggling for the weekend.

Meanwhile, Darren O’Dea is ready to step into Richard Dunne’s boots on Saturday, but does not expect to be doing so when the Euro 2012 finals come around.

The 25-year-old Celtic defender, who spent last season in the npower Championship on loan at Leeds, has 13 senior caps to his name and perhaps most notably, was part of the rearguard which somehow managed to lay the foundation for a 0-0 qualifier draw in Russia last September.

He is also currently something of a rarity at the Republic’s Malahide training base, a fit centre-half.

Giovanni Trapattoni  added McShane to his 23-man squad after seeing Sean St Ledger join Richard Dunne and John O’Shea on the casualty list.

With all three doubtful for this weekend’s friendly against Bosnia, O’Dea seems certain to start.
