Stephen Quinn has been drafted in to the Republic of Ireland squad after Paul Green was ruled out of Wednesday’s friendly encounter against England at Wembley with a hamstring injury.
Quinn, who now plies his trade with Hull City, has featured in previous squads but has yet to be capped.
Richard Dunne, who is on the lookout for a new club after Aston Villa confirmed that they will not be renewing his contract, trained with the squad at Watford’s Colney training ground in St Albans as he bids to return to full fitness.
Dunne’s last appearance for the Republic of Ireland came against Italy at Euro 2012.
The Stoke duo of Glenn Whelan and Marc Wilson are struggling with calf injuries ahead of Wednesday’s game.
The England squad have also suffered another withdrawal with Tom Cleverly forced out of the game with a calf injury.
Cleverley picked up the injury during Manchester United's final game of the season at West Brom and the Football Association confirmed tonight that the midfielder has not joined up with the squad at St George's Park.
Roy Hodgson called up Manchester City man Jack Rodwell earlier this week in case Cleverley could not regain his fitness, so the England manager will not be adding another name to his 21-man party.
With Steven Gerrard and Jack Wilshere already out through injury, Cleverley's absence restricts Hodgson's options in midfield even further.
Rodwell, Michael Carrick and Frank Lampard are the England manager's only three recognised central midfielders, although James Milner and Phil Jones can operate effectively in that position too.
