Muller out for two months
Ulster captain Johann Muller has been ruled out for eight weeks after injuring his right arm against Northampton Saints on Friday.
An x-ray on Saturday revealed that he has an undisplaced fracture of the former Springbok lock's radius.
Muller only returned for the province from a hand injury last weekend, lining out in the PRO12 win over the Scarlets.
His latest lay-off will see him miss the return fixture with the Saints at Ravenhill, the Christmas time league derbies and Ulster's closing pool games in Europe next month against Glasgow Warriors and Castres Olympique.
