The Herald reports that Andy is expected to be sidelined for up to three weeks, sustained cartilage damage in the pre-season warm-up with Newcastle Falcons. He recovered to play in last weekend's Celtic League opener against Newport Gwent Dragons but suffered a more serious injury in a midweek training-ground mishap when he collided with squad-mate Graydon Staniforth.
On the positive side, the international prop, Euan Murray, has recovered from a leg injury and is in the selection shake-up for the trip to Donnybrook. In addition the Scotland centre, Graeme Morrison, is poised to make his long-awaited return after being on the casualty list since the start of the year.
