Ulster coach Matt Williams has named the starting line up to take on Glasgow on Saturday at Ravenhill.

Williams has made five changes to the starting line up as well as one positional switch ahead of the game and had this to say about the opposition Glasgow: "They are a side who have improved enormously throughout the last season.

"They play an open and attractive style of rugby and I know some of the players well so I am looking forward to this fixture. With the week we have had, the game against Glasgow is a huge challenge"

Justin Fitzpatrick is named at loose head replacing Bryan Young who is named on the bench. In the second row Ravenhill favourite Justin Harrison is named alongside Carlo Del Fava in what could be Harrison's last start for Ulster.

The back row is all change with Neil Best replacing Kieron Dawson and Roger Wilson named at eight with Stephen Ferris unavailable due to an injury picked up on Wednesday evening.

Full Back Bryn Cunningham drops out of the squad after fracturing his cheek bone on Wednesday evening.

Williams said: "I am really disappointed for Bryn, he didn't realise the damage or complain about the pain until well after the game, it just came on him when he cooled down and proved to be a fracture."

Mark Bartholomeusz moves to full back with Scottish International Simon Danielli replacing him on the left wing, the backline remains the same as the Munster fixture with Paddy and Isaac at half backs.

Kieran Campbell is named on the bench on what could potentially be his last run out for his province before he moves to Magners League rivals Connacht.

Ulster received a lot of criticism about their line out on Wednesday night against Munster and Williams said: "We had a technically bad night, nobody is hiding from the criticism, there is no excuse.

"So far this season our line out has been solid and after Wednesday night the only thing the players can do is get back on the pitch and get it right again"

With three matches in 10 days Williams is remaining upbeat about the gruelling timetable. "Training has gone well this week, clearly the fixtures and scheduling isn't perfect but I have had no complaints from the players, they know they just have to get on with it.

"The boys showed real pride on Wednesday night in their defence and tomorrow will be no different, it will be another hard 80 minutes and mentally it is all about the heart and playing for the shirt"

Ulster need to win with Connacht still contesting Ireland's third Heineken Cup qualifying place.
