Connacht have been hit with a rash of injury worries ahead of Sunday’s Rabodirect Pro12 clash in Glasgow.
Captain Craig Clarke will be unavailable to play for an unspecified number of weeks.
The 31-year-old sustained a concussion in the Heineken Cup defeat to Saracens at Allianz Park and will be taking some time out due to the recurring nature of his injury.
Front rowers Brett Wilkinson and Sean Henry have both also been ruled out for at least four weeks due to neck injuries aggravated in the last game.
Flanker Aaron Conneely, who last played for the Eagles in their victory over Llanelli in the British & Irish Cup, suffered an ankle injury in training last week and is unavailable to play for up to six weeks.
In better news, Pat Lam's back line has been boosted by the return to training of Miah Nikora, Dave McSharry andDanie Poolman.
Both Poolman and McSharry have played in seven games each this season while Nikora has been recovering from a shoulder injury sustained in pre-season.
It is hoped that the trio will be available to play in either the PRO12 or 'A' interprovincial game (v Munster on Friday) this week.
While Robbie Henshaw remains on international duty with Ireland, Kieran Marmion and Rodney Ah You returned to Connacht training yesterday and are both available for selection.
