Ross Chisholm continues at full-back for Harlequins in Sunday's LV= Cup clash with Cardiff Blues (kick-off 1pm).

Blair: Starts for Cardiff Blues

Chisholm will be joined by Seb Stegmann and Sam Smith in the back three with the latter replacing Tom Williams.

George Lowe makes a welcome return from the injury he sustained back in November and partners Tom Casson in the centres. Karl Dickson is back at scrum-half from his long term injury, with Rory Clegg at fly-half.

Nic Mayhew starts in the front-row at loose head with Rob Buchanan and Tim Fairbrother. Chris York comes into the starting XV, replacing Luke Wallace, Tom Guest and skipper Will Skinner complete the back row.

Cardiff Blues have named a squad containing a total of 11 internationals.

Justin Burnell and Gareth Baber have selected a side with a blend of youth and experience with one eye on a busy month ahead in the RaboDirect Pro12.

The Blues twenty-three man squad includes Ben Blair, Gavin Evans, Tom James, Ceri Sweeney and Richie Rees in the backs - all of whom have played for their country.

In the forwards Maama Molitika, Scott Andrews, T Rhys Thomas and John Yapp all have international experience, while New Zealand internationals Casey Laulala and Xavier Rush are on the bench.
