Peter O'Mahony

Ireland have received massive blow ahead of next Sundays quarter final against Argentina.

Back row Peter O'Mahony has been ruled out for the rest of the tournament with a knee ligament injury.

Paul O'Connell and Johnny Sexton are also on the injured list and will undergo scans today.

Neither man has been ruled out of the next match but it's thought O'Connell is highly unlikely to face the Puma's this Sunday in Cardiff.
