Manchester United winger Robbie Brady has been added to the Republic of Ireland squad following Kevin Doyle's withdrawal.
The 20-year-old midfielder, who made his senior international debut in a 4-1 friendly victory over Oman in September, will join up with the squad ahead of a 2014 World Cup qualifying double-header against Germany and the Faroe Islands.
Manager Giovanni Trapattoni turned to the youngster after a scan on the thigh injury Doyle suffered in training with Wolves on Friday revealed the full extent of the damage.
A statement released by the Football Association of Ireland said: "The Football Association of Ireland today announced that the results of Kevin Doyle's scan showed clear signs of a muscle injury that will rule the player out of international duty for the forthcoming double-header.
"Robbie Brady, who was on standby will be called up in his place."
Brady will be joined in the squad by Sunderland midfielder David Meyler, who received a late call-up on Friday.
