Ian Nagle and Tommy O'Donnell will take no part in next weekend's RaboDirect PRO12 game against Treviso after both sustained injuries in last night's game against Zebre.

The pair will return home on Monday to continue their treatment and undergo scans to further examine their respective injuries.

O'Donnell, who was helped off after 67 minutes, suffered a hyper-extension to his left knee, while Ian Nagle suffered a sprain to his left foot.

Andrew Conway, who featured for the first half, took a knock to the groin and stays with the squad to be monitored in Italy.
