Paul O'Connell's Ireland career may be over after World Cup injury
Ireland coach Joe Schmidt fears that Paul O'Connell's international career may be over after his captain was forced off with a serious-looking leg injury in the 24-9 victory over France.
"It doesn't look great with Paul. It looks like an upper hamstring but we will probably have to wait until Monday to give it a scan," said Schmidt.
Fly-half Johnny Sexton is also set for a scan on a groin strain.
Peter O'Mahony suffered a suspected knee injury but is less of a concern.
Lock O'Connell, 35, is leaving international rugby and joining Toulon after the World Cup - having won 108 caps.
In addition to the injury worries for next Sunday's quarter-final against Argentina in Cardiff, flanker Sean O'Brien could face a citing for an alleged punch on Pascal Pape.
