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.

Ahead of Friday evening's Aviva Premiership fixture away at London Welsh, Head Coach Laurie Fisher told the local media that he feels that Gloucester are making improvements each and every week but that there's still plenty of work to do.
Speaking to GRTV on Monday night, Pete Buxton was thrilled with the spirit shown by the Gloucester United squad as they overturned a twenty-one point deficit in the second half to overcome Bristol Rugby.
Scrum half Callum Braley was a try scorer in Gloucester United's 30-27 win over Bristol United in the Aviva Premiership A League on Monday evening and, after the game, paid tribute to his team mates for hanging in there and fighting back to get the win.
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.
Gloucester Rugby is rightly proud of the work that it does within the community and is delighted to confirm that it will be working with Gloucestershire Young Carers and Pied Piper as its two chosen charities this season.
Speaking to the club website shortly after Friday night's 46-10 victory over London Welsh, Director of Rugby David Humphreys expressed his satisfaction at the result, but challenged his squad to improve their performance.
