Rory Best looks set for an extended spell on the sidelines after Ulster confirmed that he suffered a fractured forearm during Ireland's 24-22 defeat against New Zealand.
Best is due to see a specialist after he was forced to withdraw in the early stages of Sunday's game at the Aviva Stadium, just after touching down for Ireland's second try of the match,
The experienced hooker looks certain to miss Ulster's Heineken Cup double header with Treviso in December as well as Saturday's RaboDirect Pro12 trip to Zebre.
Ulster have further injury worries with the news that Iain Henderson suffered a hamstring injury in the province's victory over Edinburgh on Friday.
He will have an MRI scan this afternoon to determine the extent of the injury.
