James McCarthy remains with the Republic of Ireland squad as he battles to prove his fitness ahead of Friday's World Cup qualifier against Wales.
The Everton midfielder, who has been out of action since March 5 with a hamstring injury, warmed up with the rest of the squad at Abbotstown on Wednesday morning, but was later due to work with the physios.
Assistant manager Roy Keane admitted on Tuesday that McCarthy was unlikely to make the game if he did not train the following day, but Ireland have not yet given up on the player.
Manager Martin O'Neill and Toffees counterpart Ronald Koeman have clashed on more than one occasion over the Republic's use of McCarthy on his return from injury.
