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.

Henry Purdy, a first half replacement for Charlie Sharples, was amongst the try scorers in the 64-19 victory over Aviron Bayonnais on Saturday evening and told GRTV that it was a professional performance, one the team are happy with.
Gloucester's win in Treviso last week means that they need a bonus point win against Bayonne on Saturday evening to secure a home quarter-final (kick off 8pm), but Tim Taylor wants the team to focus on the performance first and foremost.
Billy Burns and Man of the Match Richard Hibbard spoke to GRTV after the 41-0 win in Treviso, on a day when preparations weren't ideal. They felt the team's attitude was key and also praised the travelling support.
Following the conclusion of the Stade Francais vs Harlequins game today, round six is complete and the quarter-finalists in the European Rugby Challenge Cup are now known with Gloucester set to welcome the Cardiff Blues to Kingsholm.
Knowing a bonus point win would secure a home quarter-final, Gloucester completed their European mission in some style on Saturday evening, sweeping aside a spirited but outgunned Aviron Bayonnais scoring 10 tries on their way to a 64-19 victory.
