Robbie Brady is out of the Republic of Ireland's World Cup qualifier in Moldova after it was confirmed he suffered concussion in Thursday night's victory over Georgia.
The 24-year-old midfielder spent the night in hospital after being knocked unconscious in a clash of heads with defender Solomon Kvirkvelia and although he has since been released, medical protocol means he will be able to play no part in Chisinau.
A Football Association of Ireland statement said: "Robbie Brady has been released from the squad following concussion suffered in the 1-0 win over Georgia on Thursday, October 6.
"Brady spent the night in hospital and underwent a precautionary scan, but he has been cleared by the FAI medical staff.
