The injury jinx has struck influential Ulster Rugby captain Johann Muller yet again - ruling him out of the 2012 Heineken Cup finalists' remaining Pool 4 matches.
The former Springbok lock suffered a right arm injury in the Irish club's 25-6 try bonus point victory over Northampton Saints at Franklin's Gardens last night.
An x-ray this morning revealed that he has an undisplaced fracture of his radius.
Muller had only just returned to action after recovering from a hand injury but now faces another spell on the sidelines.
He is expected to be out for at least eight weeks and will miss the Ravenhill return against the Saints in Round 4 and the ties in January against Glasgow Warriors and Castres Olympique.
