Matthew Rees will face his former club on Judgement Day
Matthew Rees will start his first match since recovering from cancer when the Blues take on his former region Scarlets in their Judgement Day II clash.
The hooker, who has 58 caps for Wales and three for the British and Irish Lions, will take on his former side in the first Judgement Day battle at the Millennium Stadium this Sunday.
The Cardiff region have made two further changes. Wasps bound lock Bradley Davies and Dafydd Hewitt, their match-winner against Edinburgh come into the starting line-up.
Rees played nine seasons for the West Wales region and will now face them for the first time since his emotional return from cancer.
The Blues have been resurgent since their captain's return, edging out Ulster at the Cardiff Arms Park before claiming a hard-fought away victory against an in-form Edinburgh.
Blues interim Head Coach Dale McIntosh hailed Rees' influence since returning from the illness.
He said: "The senior players coming back in has helped us; the likes of Gethin Jenkins, Matthew Rees, Alex Cuthbert, I think we have turned 'a' corner but not 'the' corner with recent results. We've improved and we've won two games, but it's only two games.
"We face a formidable challenge on Sunday and perhaps we will see where we really are. It's only two games we have won and we need to keep building.
"We want passion and desire from our players. We will need that tenacity and edge. That promotes accountability, firstly in training and secondly in the game. We don't players to drift through the week because what you do in training you take into the game.
"The senior players get out there and make the youngsters understand that is not acceptable. Accountability comes on the pitch when the guys are next to you on the battlefield. When he is shouting at you that is when you have to stand up and take notice."
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.
