 Isaac Boss has been on form for Ireland and Ulster |
Ulster are uncertain when Isaac Boss will be available to play again after the scrum-half sustained a shoulder injury early in the win over Glasgow. Boss underwent a scan on Monday which revealed bruising and tissue damage to the AC joint in his right shoulder.
The New Zealand-born player will continue to receive treatment but should be fit for Ireland's first Six Nations match with Wales on 4 February.
Boss had to retire after four minutes of Saturday's Magners League clash.
He is almost certain to miss Ulster's forthcoming Heineken Cup games against Llanelli Scarlets and Toulouse.
The Scarlets visit Ravenhill on Saturday 13 January and the Irish province will finish their campaign with a trip to France on Sunday 21 January.
Kieran Campbell is set to deputise in both matches.
