Munster will give an update on Peter O'Mahony's condition later in the week after further teests.
The province tweeted this afternoon that their captain’s shoulder injury would need to be assessed earl this coming week before any prognosis is made.
The Ireland flanker was forced from the field shortly after he picked up the injury in the act of stealing an early lineout . If a dislocated shoulder is confirmed, O'Mahony is unlikely to play again this season, with his chances of making Ireland's tour of Argentina this summer also up in the air.
Though Munster remain cagey as to the exact extent of the injury, the noises coming from the camp suggested the worst.
"Peter will be a massive loss for us, a brilliant captain and a brilliant leader," said lock Paul O'Connell, while coach Rob Penney said afterwards that the injury "doesn't look great".
