Republic of Ireland midfielder Robbie Brady lost consciousness during Thursday's 1-0 win in a World Cup qualifier against Georgia, manager Martin O'Neill confirmed.
The win came at a cost as Brady was carried from the field on a stretcher wearing an oxygen mask after an ugly 76th-minute clash of heads with defender Solomon Kverkvelia.
The manager of Brady: "He was out cold for a while. He's come back round again and the doctors and physios are pretty pleased with him since he was carried off.
"He 's obviously gone off at this minute [to hospital] and naturally I am hoping the lad will be fine.
