David Humphreys has been withdrawn from the Ulster team to face The Borders at Ravenhill tomorrow night after picking up a calf injury.
The Ireland international had been selected for the first time this season but will miss the Celtic League clash after straining his calf during training. Adam Larkin will replace Humphreys at out-half while Paddy Wallace provides cover on the bench.
Ulster, who have been forced to contend without a number of top players due to international commitments, continue to set the pace in the Celtic League, leading Gwent Dragons by a point eight games into the campaign.
