ULSTER v SCARLETS, Ravenhill, 8pm (live Sky Sports HD1 Interactive)
Team News: Ulster coach Matt Williams has made two changes, both in the back-line, to his side for Friday's Heineken Cup Pool 4 showdown with the Scarlets at Ravenhill.
With Fijian international Timoci Nagusa ruled out with a hamstring injury, Scotland's Simon Danielli will start for Ulster on the right wing.
Speaking ahead of his first European appearance since last January, Danielli said: "Playing for Ulster at Ravenhill is very special and when Trimby (Andrew Trimble) pulled out last week, it gave me a chance to start on the bench and then Timoci went off.
"With the amount of good players in our squad, when you get a chance you have to take it. Thankfully during the game a few holes opened up."
Danielli was sprung for the bench and ran in two tries in last weekend's 53-13 Magners League win over Connacht.
Also back to full fitness, Trimble will return to the starting line-up against the Scarlets. He has been pencilled in on the left wing in place of Mark McCrea who drops to the bench.
The province's forward selection remains the same from the Connacht game.
Looking forward to his side's return to European action, Williams said: "We are still in the Heineken Cup, we have to win all four (remaining games).
"We are playing every team in the pool and if any one of them slips up, which there is a strong chance of with Stade at 'Quins, and we win our next two games, we are in it.
"But that will mean nothing if we don't win at home. But even if we were out of it, which we are not, the attitude wouldn't change. We would still go flat out at Ravenhill.
"We have worked too bloody hard and been through too much pain and come together so far to come out at Ravenhill and just say, 'it doesn't matter'. That's just not going to happen."
This is a must-win game for Ulster who lie fourth in the Pool 4 table, with pace setters Harlequins and Stade Francais nine points ahead of them.
But Williams' charges have been boosted by recent wins over Munster and Connacht in the Magners League and Portugal in a friendly.
Meanwhile, the Scarlets' matchday squad includes four Wales players fresh from beating Australia at the Millennium Stadium - Dafydd Jones, Mark Jones, Stephen Jones and Matthew Rees.
Also back in the fold, after missing last weekend's Magners League defeat to Munster, is new Wales scrum half Martin Roberts and Wales full-back Morgan Stoddart.
Scarlets coach Nigel Davies said: "It's great to have them back. They've returned buoyed by last weekend's success for Wales and they're our most experienced, talented players so to have them all back in the group is brilliant.
"They've added a lot to everything we've done this week."
The Scarlets' long term injuries include Kees Meeuws, Gavin Thomas and Rob Higgitt, with shorter term difficulties for players such as Gavin Evans, Simon Maling and Darren Daniel.
Scott MacLeod was not considered for this game as he works to overcome a recent long lay-off.
Davies added: "We've not got much fully fit cover behind the scrum at the moment but we've still been able to put out a very strong team."

Pre-Match Quotes: Matt Williams (Ulster) - "Apart from a lapse in the first half (against Connacht), we have only let in three tries at home in five games in the Magners League, which is fantastic.
"Number two, the boys are playing with ball in hand the way I like it. They have got the confidence to do it and the way they attacked the game was fantastic.
"They scored what I term zero-tackle tries, where we get possession and we score which means we are doing a lot of good angled running and seeing where the holes are. That has come on this year enormously.
"Also our attitude was great (against Connacht). We didn't just win, we put the knife in and twisted it. We showed a lot of killer touches. They were calling 'we want 50', which was great.
"But when the Scarlets lose, they don't lose by much. Players like Stephen Jones and David Lyons are in great form, they will be tough to beat on Friday."
Nigel Davies (Scarlets) - "Friday's game is a massive one for us. We're not where we want to be in Europe at this stage but I don't think it's completely over for us.
"If we can go to Belfast and get a result then that puts us in a position where we can look forward to two back-to-back home games.
"So, if we get a result in Belfast, then who knows? There's no doubt we've got to put in a big performance on Friday.
"We're a very proud team and we're not going to hide from putting in that performance. We'll fight all the way."
