James McCarthy ruled out of Republic of Ireland qualifier due to injury

Republic of Ireland midfielder James McCarthy has been ruled out of his side's opening World Cup qualifier against Serbia due to a groin injury.

The 25-year-old missed Everton's 1-0 victory over Stoke City at the weekend, but was still called up to the Ireland squad by Martin O'Neill.

However, he has now been released back to his club to undergo further treatment on the problem, ruling him out of Monday's match in Belgrade.

"Midfielder James McCarthy returned to his club following assessment from the FAI medical staff as he recovers from a groin injury," read a statement from the Football Association of Ireland.

McCarthy had been heavily linked with a move away from Everton on transfer deadline day, but ended up staying at Goodison Park.
