Cardiff Blues have made a late change to the twenty two to face Glasgow Warriors this Saturday.
Ben Blair and Richie Rees have withdrawn from the squad, both suffering with their hamstrings. However, both players will be available for the Harlequins match.
Leigh Halfpenny moves from the bench to play at Fullback, while Darren Allinson replaces Richie Rees on the bench at Scrum Half.
Chris Czekaj moves onto the bench in place of Halfpenny.
