Cardiff Blues have named Leigh Halfpenny on the bench for their next game. The Wales wing has been out with an ankle injury since October, but back-row Xavier Rush (neck) is out despite completing a one-week suspension.

Centre Jamie Roberts makes his first start since surgery on a long-term wrist injury, replacing Tom Shanklin.

The Ospreys promote Andrew Bishop, Jamie Nutbrown, Paul James and Ian Gough to the starting line-up.

All four started on the bench in Monday’s 60-17 win over the Scarlets but get their turn to start at the Blues, with Nikki Walker, Mike Phillips and Ryan Jones dropping to the replacements.
