GLOUCESTER will welcome back two of their most important and inspirational figures tomorrow when they host Bristol at Ashton Gate (3.05pm).
Both James Simpson-Daniel and Andy Hazell will return to the starting line-up having missed the 19-12 defeat at Newcastle a fortnight ago as Gloucester aim for top spot in the Guinness Premiership.
Hazell's influence has been stratospheric for Gloucester all season. He will require only four more tackles tomorrow to top 200 for the season and heads the Premiership tackle count - 14 ahead of team-mate Peter Buxton.
The openside flanker will line-up alongside Buxton and James Forrester in Gloucester's row.
Simpson-Daniel, meanwhile, will make his 15 Premiership appearance of the season and his first at outside centre because of the injury to Mike Tindall. He will partner Anthony Allen in Gloucester's backline that is reshuffled because of injury.
James Bailey, who is Gloucester's leading Premiership try scorer with five, is ruled out with a groin injury which means Iain Balshaw switches to the wing and Willie Walker comes in at full-back.
Peter Richards starts at scrum-half and will partner Ryan Lamb at half-back.
"Tomorrow will be a history making occasion for Gloucester but the vibe about Ashton Gate is really, really positive and something we are all looking forward to," head coach Dean Ryan told www.gloucesterrugby.co.uk
"It is a fantastic stadium, there will be more than 12,500 Gloucester supporters inside the ground and the atmosphere generated will be like Kingsholm on the road.
"There is a significant amount on this match for both teams. We were exceptionally disappointed with aspects of our defeat at Newcastle and I expect to see a reaction from that.
"When you look back at the last 12 months it is possible to see how far this group has come. I think it is testament to the squad we are building we are in this position and we now need to take that into knockout rugby.
"We are delighted to have both Andy Hazell and James Simpson-Daniel back in the side because they have experience of big, one-off matches and that is vital at this stage of the season."
In the forwards, Ryan is able to name a settled line-up. Nick Wood, Olivier Azam and Carlos Nieto form the front row, while Alex Brown returns in the second row alongside skipper Marco Bortolami.
On the bench there are returns for Christian Califano, who broke his thumb against Northampton at the start of March and Jack Adams. Gloucester will make a decision tomorrow on their back row replacement between Jake Boer and Luke Narraway.

Ben Morgan was on media duty this week, and as Gloucester prepare for Sunday's trip to Wasps, the number eight is looking forward to see Gloucester go toe-to-toe with another of the Aviva Premiership's front runners.
Tom Marshall scored his first Gloucester try in the 31-23 win over Saracens on Friday evening and was named Man of the Match. Talking to GRTV, he praised the forwards for setting the tone on the night.
Matt Scott was on media duty this week, and the Scottish international spoke about the benefit of having a full week of training with his club mates and the determination to get back to performing well against Saracens this Friday evening.
After the disappointment of last weekend's performance at Leicester, Director of Rugby David Humphreys told GRTV that he expects a big response from Gloucester in Friday's Aviva Premiership fixture at home to Saracens (kick off 7:45pm).
Gloucester were competitive for long periods at the Ricoh Arena on Sunday afternoon, but were left to rue a host of missed scoring opportunities throughout as Wasps hit back to earn a 35-22 Aviva Premiership win.
Gloucester's Ciaran Knight made his first start at tighthead prop, Henry Walker made his first appearance as a second half replacement and Alex Seville also featured as England U20s might it three from three in the U20s Six Nations with a 46-0 win over Italy in Darlington on Friday night.
