Ulster’s Paddy Wallace and Pedrie Wannenburg are expected to be available for selection for this weekend’s Heineken Cup semi-final against Edinburgh which will be played at the Aviva Stadium on Saturday (28 April). Paddy Wallace was feeling unwell during the game and left the field having suffered visual disturbance due to migraine which resolved within an hour of on-set. Pedrie Wannenburg sustained a groin injury which is responding well to treatment. Chris Henry sustained an ankle sprain which is subject to ongoing treatment and re-assessment but at this stage he is not ruled out of contention. Paul Marshall continues to receive treatment for the injury to his right elbow sustained in the match against Connacht and re-assessment is ongoing.
