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.

As Gloucester prepare for their 39th game of the season, against Bordeaux-Begles at Sixways on Sunday, David Humphreys told the local media that this week has been all about getting the players mentally and physically ready after a tough game against Connacht last Sunday.
Speaking to GRTV after the 40-32 victory over Connacht on Sunday, skipper Billy Twelvetrees explained that Gloucester had had to learn to be patient and cut out the errors to earn the win and progress to next weekend's final play-off against Bordeaux-Begles.
Jonny May's superb late score capped a thrilling 40-32 European play-off win over Connacht on Sunday. The winger spoke afterwards of his team's character and spirit as he looked ahead to one more week of rugby.
Speaking to GRTV this afternoon, Director of Rugby David Humphreys hailed the 'never say die' attitude of the team, after despite not being at their best, fighting back to take a 40-32 win after extra time over Connacht.
Jonny May continues on the wing on Sunday as Connacht come to town, and the England wing explains to the local media this week that he is delighted with his form and is looking forward to taking on Pat Lam's men.
