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.
The 19 year-old has already represented England U19s. He was set for a full 80 minutes against Saracens in the Zurich 'A' League last week, but the game was postponed, but he went on to play for Bracknell in the national leagues last weekend.

Skipper Billy Twelvetrees admitted that the Gloucester squad were disappointed and frustrated after losing at home to Exeter, regretting that Gloucester's own errors had given the Chiefs the upper hand.
David Humphreys spoke to the local press after the Gloucester Rugby team to face Exeter Chiefs on Friday was announced. Henry Purdy is making his Premiership debut for Gloucester and thoroughly deserves his chance says Humphreys.
Dan Murphy was part of a Gloucester pack which took a grip as the Sale game progressed and, ultimately, were rewarded with a late penalty try. The loose head prop says the team's improved scrummaging is down to a lot of hard work over the summer.
Gloucester clinched their first Aviva Premiership win of the season on Saturday, 34-27 over Sale Sharks, and scrum half Greig Laidlaw felt that the Kingsholm crowd played a massive part as they spurred the team on.
David Humphreys spoke to Gloucester Rugby TV after the 34-27 win over Sale Sharks at Kingsholm. The Director of Rugby praised the Kingsholm crowd for spurring the team on to a super second half comeback.
