Aston Villa have apologised to Giovanni Trapattoni's Republic of Ireland medical team over their criticisms of Richard Dunne.
Villa were heavily critical of the treatment received by Dunne, 32, for a groin injury during Euro 2012.
The Premier League side claimed the Ireland medical staff had not treated their player correctly, causing the central defender to have surgery which would sideline him for two months.
However, Villa have now back-tracked and admitted to making an error of judgement over the criticisms.
In an official statement on their website, the club said: "In a press release dated August 1, 2012, Aston Villa Football Club made a number of assertions and comments about the medical treatment received by Richard Dunne during his service with the Ireland team during the European Championships.
"We wish to acknowledge that Richard Dunne received the highest standard of medical care before and during the Championships and apologise to those involved in providing his treatment if any other impression was erroneously given."
Dunne played in all three of Ireland's games in Poland and Ukraine as Trapattoni's side failed to make the last eight of the competition.
The Football Association of Ireland responded to Villa's original accusation with a strongly-worded statement.
It read: "Richard Dunne received the highest level of medical care during his time with the Republic of Ireland team. All of the medical treatment he received was carried out in full and regular contact, and with the full consent and agreement of, the Aston Villa medical team and so we are very surprised by these suggestions."
