ULSTER (3rd) v SCARLETS (6th), Ravenhill, 7.15pm (live BBC 2 Northern Ireland/BBC 2 Wales)
* Please note: Tonight's game between Ulster and Scarlets at Ravenhill will now kick off at 7.15pm, ten minutes later than originally scheduled.
Team News: Paddy Jackson, who scored his first try for Ireland last Saturday, has been released from international duty and will start for Ulster against the Scarlets at Ravenhill on Friday.
Jackson's inclusion is one of four personnel and three positional changes to the side that defeated the Ospreys in Belfast last weekend.
Jared Payne moves from outside centre to full-back with Darren Cave reverting to his more familiar role in the number 13 jersey. Craig Gilroy continues on the right wing with Michael Allen keeping his place on the left.
Luke Marshall starts at inside centre alongside Cave, with Jackson at out-half and Ruan Pienaar, who played his 75th game for Ulster against the Ospreys, named at scrum half.
There are no changes to the front row where Tom Court, Rob Herring and John Afoa all start, while Johann Muller captains the side from the second row where Iain Henderson partners him.
Roger Wilson moves across the back row to blindside flanker, with Sean Doyle continuing at openside and Nick Williams coming in at number 8.
Robbie Diack and Ricky Andrew, who both started last time out, are named among the replacements.
Ulster have lost just once at Ravenhill in the past 12 months, however, the Scarlets beat Mark Anscombe's men in Llanelli earlier in the season.
The round 14 match is sold out - the tenth game to be sold out at Ravenhill this season.
Meanwhile, a six-try 41-33 victory away to Benetton Treviso has gone a long way to building confidence and belief in the Scarlets squad ahead of their visit to Belfast.
Scarlets boss Simon Easterby has made only two changes to the team that took on Treviso last weekend.
Tighthead prop Samson Lee comes into the starting line-up for Jacobie Adriaanse, having been released back to the region from the Wales camp, and second row Johan Snyman replaces Richard Kelly who drops back to the replacements bench.
Number 8 Rob McCusker, who captains the Welsh region, will be looking to fire up his team to secure a performance and a result against a strong Ulster side.

Pre-Match Quotes: Tom Court (Ulster) - "It (the Ospreys game) was probably one of the coldest and bleakest nights that I have played in in a good while. There's not a lot to take from it other than we have to get things right for this week or there is a good chance that we will get beaten.
"The Scarlets will be coming over here with a sniff of being able to turn us over. They are a very professional team and I imagine that they will use their defeat to us in last season's PRO12 play-off as an incentive to spur them on this week.
"They have been playing well - consistently well all year, especially through the forwards and they will be looking to get stuck in.
"We have had great momentum and we just have to try and keep that going. In the past we have had a lot of issues with the international period lag, where during the Six Nations and immediately after we have had a drop in form and it has taken us a few weeks to get back in the swing of things.
"Luckily we haven't had as many injuries this year. It is up to the younger players this year to set up, to fill the void, to take their opportunities and to keep the momentum going."
Simon Easterby (Scarlets) - "We're going to Ravenhill under-strength but we have to be confident that we can back up what we did in Treviso last Friday.
"We've put into place some of the stuff we did well out here against them earlier in the season and Friday's game is one that we can go and win.
"There are very few games that we can afford to drop points in. There are 45 points up for grabs and there are sides around us that will win and lose over the next three rounds. We've given ourselves a fighting chance with that victory last weekend.
"There's a way of trying to beat Ulster and there's a way of trying to stop them as well. We need to be as good as we've been when at our best this season to secure a victory."
