ULSTER v GLASGOW WARRIORS, Ravenhill, 3pm
Team News: Ulster coach Matt Williams has made five changes to his side as well as one positional switch ahead of this game against Glasgow.
Justin Fitzpatrick will start against the Scots at loosehead prop, replacing Bryan Young who drops to 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 before his move to Bath.
The back row is all change with Neil Best replacing Kieron Dawson and Roger Wilson named at number 8 with Stephen Ferris unavailable due to an injury picked up during Wednesday's win over Munster.
Full-back Bryn Cunningham drops out of the squad after fracturing his cheekbone on Wednesday evening, with Mark Bartholomeusz set to don the number 15 jersey and fit-again Scottish international Simon Danielli coming onto the left wing.
With Isaac Boss again starting at scrum half, Kieran Campbell has been named on the replacements bench ahead of what could be his last run-out for the province before his switch to Connacht.
Meanwhile, Glasgow have made two changes to the sides that edged out Llanelli last time out. In the back-line, Lome Fa'atau comes in for Daryl Gibson with Max Evans moving to outside centre.
The other change is at hooker where Dougie Hall starts in place of Fergus Thomson.
The visting side also includes three players - Kelly Brown, Thom Evans and Dan Turner - who recently put pen to paper on new contracts with the Scottish club.

Say What: Matt Williams (Ulster) - "Glasgow 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. 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 (against Munster) on Wednesday night in their defence and Saturday will be no different. It will be another hard 80 minutes and mentally it is all about the heart and playing for the shirt."
Sean Lineen (Glasgow Warriors) - "(Commenting on the players to re-sign for the club) Kelly Brown has been nothing short of inspirational and Dan Turner has created real competition with Alastair Kellock, which is what every coach wants. Dan never gives anything less than 100%.
"As for Thom, he's a classy international player in the making. It was crucial that we kept him, he's a real crowd pleaser."
Top Scorers: 2007/08 Magners League - Points: Ulster: Niall O'Connor 54; Glasgow Warriors: Dan Parks 138; Tries: Ulster: Tommy Bowe, Ryan Caldwell 3 each; Glasgow Warriors: Dan Parks 5.
