Stoke City defender Marc Wilson has emerged as an injury concern ahead of the Republic of Ireland's forthcoming international fixtures.
Giovanni Trapattoni's Boys in Green face into a packed fixture schedule in May and June, with friendlies against England, Georgia and Spain, as well as a World Cup qualification game against the Faroe Islands to play over the two months.
Wilson, 25, limped off during the Potters' victory over Queens Park Rangers at the weekend with a recurrence of a hamstring strain, casting doubts over the player's potential involvement in upcoming games.
Stoke boss Tony Pulis admitted that he had concerns over the fitness of Wilson, as well as his team mate Matthew Etherington, who is suffering from back problems and suggested that the pair would miss the remainder of the season.
"Both of them are having intensive treatment and it's a case of keeping everything crossed for them," he told reporters. "They are clearly a concern, and at this stage we don't know when, or if, they will be back."
The Republic of Ireland play England at Wembley on May 29, before hosting Georgia at the Aviva Stadium on June 2.
Trapattoni's Boys in Green will then host the Faroe Islands in a World Cup qualification game on June 7, before facing world and European champions Spain in a friendly at Yankee Stadium, New York four days later on June 11.
