GARTEH COOPER will start his second Guinness Premiership match of the season at scrum-half when table-topping Gloucester travel to Newcastle on Sunday (3pm).
The Wales number nine comes into the team for Rory Lawson in one of three changes to the side that beat Bourgoin 51-27 at Kingsholm last Saturday.
Marco Bortolami returns to the second row as captain in place of Peter Buxton, who moves to the bench and Alasdair Strokosch starts at number six which means Luke Narraway shifts to the openside in place of Akapusi Qera, who is ruled out with a slight wrist injury.
The rest of Ryan's line-up remains intact for what potentially could be one of the most exciting games of the season between two sides stacked with English talent.
"It is impossible to believe we can operate with the same group of players relentlessly throughout the season because we have been through a very intense period of matches and we are not going to get the best from a guy like Pete Buxton if we simply play and play him," Ryan said.
"We are bringing in an international captain and outstanding player in Marco Bortolami to the second row, Gareth Cooper has looked sharp in his appearances from the bench and Strokosch gives us a work ethic and explosive power we will require.
"Newcastle away from home is one of the most demanding fixtures in the Premiership - they have an outstanding spine to their team and world class players in key areas - it is a hugely important game for both of us.
"I think both teams like to try and play rugby in the right way and that is a great endorsement to both clubs and also the Premiership."
Bortolami's last start was against the Dragons in the EDF Energy Cup at the end of November and he will partner Alex Brown at lock. The front row of Nick Wood, hooker Olivier Azam and tight-head Carlos Nieto remains intact.
Narraway, who has operated at numbers eight and six this season switches to the openside flank, Strokosch comes in at six and Gareth Delve will start his fifth successive game at number eight.
Outside Cooper, Ryan Lamb will wear number 10 and will face Jonny Wilkinson, Anthony Allen and Mike Tindall feature in midfield, while Lesley Vainikolo, the Premiership's leading try scorer with seven; James Simpson-Daniel and Iain Balshaw complete the back three.
The bench is again made into a four-three forward split. Andy Titterrell and Patrice Collazo are the front row replacements and Will James and Buxton the back five options.
Scrum-half Lawson, utility back Willie Walker, who scored against Bourgoin last Saturday and Leon Lloyd complete the three-quarter options.
GLOUCESTER (v Newcastle, Sunday): Iain Balshaw, James Simpson-Daniel, Mike Tindall, Anthony Allen, Lesley Vainikolo; Ryan Lamb, Gareth Cooper; Nick Wood, Olivier Azam, Carlos Nieto, Marco Bortolami (capt), Alex Brown, Alasdair Strokosch, Luke Narraway, Gareth Delve. Reps: Andy Titterrell, Patrice Collazo, Will James, Peter Buxton, Rory Lawson, Willie Walker, Leon Lloyd.
Following the 48-10 Aviva Premiership win over London Welsh on Saturday, Dan Murphy praised his team mates for battling right up to the very last minute in difficult conditions and maintaining the momentum that the team have built in 2015.
Henry Purdy scored two memorable tries against London Welsh at Kingsholm on Saturday, and attributed the first one to hard work on the training ground before describing how much he's enjoying playing his rugby alongside friends like Callum Braley.
Gloucester face London Welsh for the third time this season when they meet at Kingsholm in the Aviva Premiership on Saturday (kick off 3pm), but Director of Rugby David Humphreys insists his team are prepared for a tough game against the Exiles.
Billy Burns was a late call up to the Gloucester team that lost narrowly to the Leicester Tigers at Welford Road on Friday evening and, speaking to GRTV post match, was full of praise for his team-mates but admitted that defeat was tough to take.
Speaking after what he described as an 'arm wrestle' up front, skipper Tom Savage couldn't fault his side's effort and commitment on the night at Welford Road but insisted that his side will keep on battling, starting at home to London Welsh next weekend.
A number of the Gloucester Rugby squad this week benefitted from an initiative organised by Circle 2 Success (C2S) and the Rugby Players Association (RPA) to help players develop their business planning skills.
