Ulster coach Brian McLaughlin welcomes Tom Court back from international duty for his side's Magners League encounter with Glasgow Warriors at Ravenhill today.
Test-capped trio Court, Timoci Nagusa and Simon Danielli, who replaces Andrew Trimble on the wing, all return following November’s international break.
But Paddy Wallace sustained an ankle injury while on Ireland duty so Ian Whitten will team up with Darren Cave in the centre.
Andy Kyriacou replaces Nigel Brady at hooker, while Declan Fitzpatrick starts at tighthead prop and BJ Botha has recovered from a knee injury to complete the front row.
David Pollock makes his first start of the season in the second row alongside Dan Tuohy, a recent Ireland A debutant.
McLaughlin said: "The next five games are vital, we have no time to waste in getting our focus back and right.
"This week the aim has been getting everyone on the same page, to take us forward into phase two which is going to be very important for Ulster.
"Glasgow are certainly a strong team, they are level on points with us in the Magners League.
"They also had eight players in action for Scotland during the autumn internationals, and of course Scotland had that magnificent win over Australia.
"There can be no doubt that it is going to be a very tight game. Obviously their three key players are the half-backs Dan Parks and Chris Cusiter, and also (Johnnie) Beattie at number 8. They have a very strong scrum as well. It is going to be an exceptionally tough game for us."
He added: "The Ravenhill crowd, the supporters, they are just tremendous. Right from pre-season the whole way through they have given magnificent support.
"So, we are really looking forward to getting back to Ravenhill, after being away for over a month now. We need a big performance for the supporters and we need to build a solid platform for Stade (Francais) the following week."
