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.

Willi Heinz scored Gloucester's second try as the Cherry and Whites overturned a disappointing first 40 minutes and 0-6 half time deficit, to earn a 26-18 Aviva Premiership victory over Bristol Rugby on Saturday.
It's the first Gloucester-Bristol derby at Kingsholm in over eight years this Saturday (kick off 4:30pm) and, previewing the game with the local media this week, Defence Coach Jonny Bell stressed that, with both teams in the bottom half of the table, they both need the points.
Speaking to the local media this week, Gloucester front rower John Afoa knows the challenge ahead this week against Bristol, and calls on the Cherry and Whites to make the most of home advantage as a determined squad look to bounce back from a narrow loss to Saracens.
Tom Savage speaks to GRTV and the local media as Gloucester went down by 24-20 at Saracens on Sunday afternoon. The second row was disappointed with the result, despite a strong showing from the hosts.
Speaking immediately after the game, skipper Willi Heinz thought that Gloucester had executed their game plan reasonably well and competed hard against Saracens. However, it wasn't enough but the squad will have plenty to work on this week ahead of the derby match against Bristol.
Gloucester may be coming off their best win of the season, the 38-16 victory over Wasps last weekend, but Director of Rugby David Humphreys admits that Sunday's trip to Saracens is an even tougher test.
Gloucester centre Billy Twelvetrees praised his side's character after their comeback win against Bristol on Saturday. The Cherry and Whites overcame a 6-0 half time deficit to eventually win the game 26-18 and secure a bonus point victory.
