Cardiff's team to play Cross Keys at the Arms Park on Saturday shows only one change in the starting line-up from the side that beat Pontypool 36-6 last week.
Rhys Williams comes in for Roger Davies at full back in what will be his 184th game for Cardiff or the Blues.
Team administrator Keith Morgan said, "We were obviously very pleased to come away from Pontypool Park with a bonus point victory and the coaching staff understandably believe that the bulk of the team should start again this week. The only minor tweak is that Roger and Rhys are reversing their roles from Pontypool where Rhys began on the bench."
Two additions to the replacements are prop Phil Osborne and the return of Damian Welch after IRB Sevens' duty with Wales in Dubai last month.
This season's first fixture between Cardiff and Cross Keys was postponed after an unseasonal monsoon in early September left Pandy Park waterlogged. Last season Cardiff completed a Premiership double, following up a 35-21 win at Cross Keys with a 23-19 victory at the Arms Park last January.
Team: Rhys Williams; Ryan Howells, Gareth Chapman, Darren Ryan, Chris Czekaj; Gareth Davies, Owen Ruttley (captain); Scott Roberts, Garry Horrigan, Kristian Gay, Matthew Veater, James Down, Adam Powell, Craig Everett, Rhys Shellard.
Replacements: Kieran Crawford, Ian George, Phil Osborne, Damian Welch, Lee Jarvis, Garyn Lucas, Roger Davies.
As the countdown continues for RWC2015, Tournament Chief Executive Debbie Jevans visited the Millennium Stadium to discuss preparations for the eight matches and reveal the positive news that 100,000 tickets for games at the home of Welsh rugby have sold in the last seven days.
Jason Harries is targeting a first win on the World Series circuit this season with Wales. The series returns to action this weekend in Dubai where Harries is part of a team hoping to build from its efforts in round one in October.
Wales skipper Jevon Groves says his side have addressed a few points from Gold Coast and aim to 'hit the ground running' in the next two rounds of the World Series, kicking off with this weekend in Dubai before heading off to South Africa next week.
Wales Sevens manager Steff Thomas is hopeful his side can build from a quarter-final spot in the opening round of the World Series in Australia when his side take part in the forthcoming double header in Dubai and South Africa.
