Ulster Rugby have a number of injury concerns arising out of Saturday's Round 2 Investec Champions Cup defeat to Union Bordeaux-Bègles.
Iain Henderson, Cormac Izuchukwu, Nick Timoney, Werner Kok, Nathan Doak and Aidan Morgan all picked up injuries that will be monitored through training this week to ascertain their fitness to play in Friday's URC fixture against Munster.
There are also ongoing doubts around the availability of Ben Carson and Stewart Moore, who were both injured in the Champions Cup Round 1 game against Toulouse.
John Cooney has resumed full team training and is available for selection.
