Injuries have ruled out both Rory Best and Paddy Wallace from the trip to Glasgow. Nigel Brady has been named in the squad replacing Rory Best while Jamie Smith returns to the squad from injury.
Commenting on the Magners League clash, Ulster Coach Brian McLaughlin said: "We're travelling to Glasgow this afternoon by boat as the airports are now closed and we're about to have our Captain's Run at lunchtime. We had a good review of Tuesday nights game against the Ospreys and we've got to look at our defence, we're still suffering from inconsistency around our defence. For Andrew Trimble's try our defence was magnificent and for Simon Danielli's try that also came from a defensive turnover so we have to be more consistent in defence. Our set piece on Tuesday night was a lot more solid, we just have to stop giving away soft tries, Shane Williams' try was a prime example and we gifted James Hook two tries under the posts so we must improve in this aspect of our play.
"Glasgow are another quality side and we're expecting a very tough game, it's been a quick turnaround for us, physically we're in good shape so now we just have to get the boys mentally right for this very important game"
