ULSTER (5th) v EDINBURGH (9th), Ravenhill, 7.05pm (live BBC 2 Northern Ireland/BBC ALBA)
Team News: Ireland internationals Craig Gilroy and Iain Henderson have recovered from injury and have been named in Mark Anscombe's starting line-up for the game against Edinburgh at Ravenhill.
The fit-again Gilroy starts at full-back alongside Andrew Trimble and Michael Allen in the back-three, as the province return to RaboDirect PRO12 action.
Luke Marshall and Darren Cave have both been released by Ireland and start in the centre with James McKinney and Paul Marshall selected at half-back.
Callum Black, Rob Herring and John Afoa are named in an unchanged front row, with Lewis Stevenson and the returning Henderson starting in the second row.
Robbie Diack captains Ulster for the first time and is selected at blindside flanker. Sean Doyle, who was man-of-the-match for the Ravens against Connacht Eagles last Friday, is picked at openside flanker and Nick Williams starts at bumber 8.
Ireland internationals Tom Court, Dan Tuohy and Roger Wilson are named on a strong replacements bench which also includes Niall Annett, Ricky Lutton, Ian Porter, Peter Nelson and Ricky Andrew.
Commenting on this opportunity to captain Ulster for the first time, Diack said: "It was a bit of a shock when Mark (Anscombe) called out the team and I was captain, but it is a tremendous honour.
"I am hugely excited to be leading out such a talented bunch of guys and hopefully we can get the win."
* Nick Williams and Ian Porter have been ruled out of this evening's match against Edinburgh after they both picked up injuries in training.
Williams suffered a recurrence of the calf injury that he sustained last month, while Porter is out with a shoulder injury. As a result, Roger Wilson is promoted from the bench to the starting line-up with Mike McComish now named as a replacement.
With Michael Heaney also unavailable due to injury (AC joint), Hughes Insurance Ulster Academy scrum half David Shanahan is named as one of the replacements. The Ireland Under-20 international is in line to make his first appearance for the senior Ulster side if called upon.
Meanwhile, Edinburgh boss Alan Solomons has made two changes to the side that will run out against Ulster in Belfast.
The match is the first time the South African has faced the province he successfully coached for three seasons (2001 to 2004) since moving to Edinburgh in August from Super Rugby outfit Southern Kings.
Second row Ollie Atkins is handed his first start in the place of Grant Gilchrist, who is starting for Scotland in Saturday's game against Australia, while scrum half Sam Hidalgo-Clyne comes in for the injured Sean Kennedy (knee), with Grayson Hart poised to make his debut from the bench.
Ben Toolis could also come on to make his debut as replacement lock, while full-back/winger Tom Brown returns to the squad for the first time since injuring his ankle in a pre-season clash with Newcastle Falcons in August.

Pre-Match Quotes: Mark Anscombe (Ulster) - "It (the 17-9 loss to the Scarlets) was disappointing and it wasn't acceptable. It was a below power performance but what we have got to do is bounce back from that.
"We have not made excuses for what happened. We have addressed the things we needed to as a team and an organisation and now we have to make sure we do not repeat what happened.
"Edinburgh have got some good footballers in their team. We have to respect that, but the thing we have got to do is make sure we execute the things we've been talking about and the game that we want to play on Friday night."
Alan Solomons (Edinburgh) - "I'm certainly looking forward to going back to Ravenhill. I've got very fond memories of Ulster and haven't been there for a number of years, so I'm really looking forward to it.
"Away fixtures in the RaboDirect PRO12 are always tough and Ulster are a side that have been built over 10 or 12 years to become one of the top sides in Europe.
"They were in the PRO12 final last year, the Heineken Cup final the year before that and have ambitions to win these competitions. We are a side that is rebuilding and are at a different place at this point.
"For me, this is going to be a really tough fixture but presents these players with an opportunity to build on their performance against Zebre in a tougher fixture, against a highly ranked side at a very tough venue."
