GLOUCESTER (2nd) v MUNSTER (1st), Kingsholm, 6pm (live Sky Sports 2 HD/Newstalk/highlights TG4)
Team News: Head coach Rob Penney has made six changes to the side beaten by Ulster, with Conor Murray the most notable inclusion as Munster travel to Gloucester for a crucial Heineken Cup round 5 fixture on Saturday.
Murray is set to win his 50th cap in his first appearance since injuring his knee against Perpignan five weeks ago.
Hooker Damien Varley retains his place in the starting line-up despite limping off at Ravenhill with a foot injury, but it is not as bad as first feared and Varley is fit to start.
Aside from returning scrum half Murray, there are three other changes in the backs with Keith Earls, Johne Murphy and James Downey all resuming behind the scrum.
Earls is back on the right wing after missing out last week with a bruised shoulder with Downey, who was sidelined with an irritated groin, returning to partner Casey Laulala in the centre.
Murphy comes into the side on the left wing with out-half Ian Keatley and full-back Felix Jones keeping their places in the side.
There are two changes in the forwards as BJ Botha and David Foley are drafted into the pack. It will be a a big day for Tipperary man Foley as it is the lock's first appearance in the Heineken Cup.
Penney has gone for an all-international front row with props David Kilcoyne and South African Botha either side of Varley.
Foley is included after impressing off the bench against Ulster last time out and he partners Ireland captain Paul O'Connell in the second row.
The back row remains unchanged with Munster skipper Peter O'Mahony, Tommy O'Donnell and James Coughlan in good form heading into the Kingsholm showdown.
Simon Zebo is named on the bench as he returns to the province's matchday squad for the first time since cracking a bone in his foot against Edinburgh in October.
Donncha O'Callaghan and JJ Hanrahan are also among the replacements after overcoming their recent injury issues.
Meanwhile, former Ireland Under-20 winger Shane Monahan will make his first Heineken Cup start for Gloucester against Munster this weekend.
Monahan's return on the left wing is one of a number of changes that director of rugby Nigel Davies makes to the Gloucester side that started against Saracens last weekend.
In the back-line, Jonny May moves from the left wing in to outside centre and Dan Robson gets the nod at scrum half.
Up front, Yann Thomas and Darren Dawidiuk are selected at loosehead prop and hooker respectively and Gareth Evans will start at number 8.
Evans replaces Ben Morgan who has battled to overcome a knock picked up against Saracens, and who will line up amongst the replacements.
Also back in the matchday squad for the first time in several weeks is Tongan international Sione Kalamafoni, who returns from injury.
After two wins in the Aviva Premiership, Gloucester slipped to a 29-8 defeat at home to Saracens which was a setback according to Davies.
"It was disappointing, because even though we're nowhere near where we need to be, we've been competitive in matches in the majority of cases," he said.
"So, we've worked through that, and the players have acknowledged that they didn't put in the performance that the shirt and the supporters deserve.
"We've got a lot to do this week to make sure that everybody sees that the shirt, the venue, the supporters mean everything to this group of players."

Pre-Match Quotes: David Kilcoyne (Munster) - "Gloucester are a side steeped in tradition, they're a bit like us in that they take huge pride in their forwards and in their set piece.
"They got beaten badly (by Saracens) last week in front of their home crowd so they'll be gunning for blood this week and we've a mammoth task ahead of us going over there. They don't want to be beaten twice, especially at home.
I definitely think Gloucester will be wise to it - any team doing match analysis after that (Ulster) game will see that we got two scores off the maul and a third that was disallowed or whatever.
"We do live mauling every (week). Axel (Anthony Foley) and Rob (Penney) put huge emphasis on our scrum and our maul and lineout.
"It is the foundation of what Munster is built on. To get tries against Ulster on the back of it was great. It is an area Gloucester will target and try and eliminate for us."
Charlie Sharples (Gloucester) - "It will be a massive challenge for us, but one thing we have learnt from (last weekend's Aviva Premiership loss to) Saracens is we have to step our game up.
"Munster are similar to Saracens in the respect that they're a very clinical team. They have a good set of forwards, a solid set piece, good defence and are generally a very difficult team to play.
"It's not a massively flash game but they're good at what they do and when it goes behind to the backs in a broken field they throw the ball around.
"We'll look at the things that didn't go well against Saracens and learn from them. Then we'll look at Munster in detail and try to put on a better show."
