Gloucester's Mefin Davies and Olly Morgan will also be in international action this weekend with Wales and England U21s respectively.
32 year-old Mefin Davies has been selected at hooker for Wales in their massive Six Nations opener against England and his Gloucester colleagues Andy Hazell, Phil Vickery and James Forrester.
Davies starts for Wales ahead of Robin McBryde, who has recently returned from injury. He starts alongside props Adam Jones and Gethin Jenkins.
Gloucester Academy star Olly Morgan is in contention for the full-back slot for England U21s against Wales in Newport on Friday night.
