The Blues will be looking for a repeat performance against the Exeter Chiefs having already recorded a 26 point to 21 win over Exeter in a pre season friendly in Devon.
The Welsh Guards have already enjoyed a visit to the Cardiff City Stadium this season when they performed a demonstration to rapturous applause ahead of the Blues v Scarlets match in October.
The Cardiff Blues v Exeter chiefs match will also see a special collection being held for two service charities, the 2010 Poppy Appeal and Help for Heroes.
The 2010 Poppy Appeal is about helping the Afghan generation of the Armed Forces and their families - today and for the rest of their lives. The British Legion has committed £25 million to the Personnel Recovery Centres, including £12 million to The Royal British Legion Battle Back Challenge Centre, a facility being built to enhance the recovery of wounded, injured and sick Service personnel.
Since 2003 the Legion has helped more than 10,000 Serving, ex-Service and family members who are part of the Afghan and Iraq generation.
Help for Heroes was launched on 1st October 2007 with the initial aim of raising funds for the Defence Medical Rehabilitation Centre Headley Court in Headley, Surrey. The new complex houses a gymnasium and full-sized swimming pool. Help for Heroes has provided £8M to build the Rehabilitation Complex which was opened by Prince William on 4 June 2010.
Help for Heroes has also donated £520,000 to the SSAFA Forces Help "Home from Home" appeal to provide a relatives house at Selly Oak Hospital and Headley Courtt allowing families can be close to their relatives while they are recovering.
Speaking ahead of the match, Cardiff Blues Scrumhlaf, Lloyd Williams said,
"We are delighted to be supporting two very worthy charities at our match against Exeter and it's great that members of the Armed Forces can attend the match for free."
"Both charities do fantastic work looking after former members of the armed forces and I think it's important that we remember them especially at this time of year."
The Blues will also be facing Exeter, Bath and the Ospreys in this year's Anglo Welsh competition.
