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.

Gloucester have been in good form in recent weeks, but Backs Coach Tim Taylor knows that the Cherry and Whites will have to be at their best on Thursday evening (kick off 7:45pm) against a Stade Rochelais side flying high this season.
Speaking to GRTV after the bonus point win over Bristol, back row Lewis Ludlow revealed that despite a tricky first half, Gloucester backed their skills to come through, a faith that was evident in a strong second half showing.
Willi Heinz scored Gloucester's second try as the Cherry and Whites overturned a disappointing first 40 minutes and 0-6 half time deficit, to earn a 26-18 Aviva Premiership victory over Bristol Rugby on Saturday.
It's the first Gloucester-Bristol derby at Kingsholm in over eight years this Saturday (kick off 4:30pm) and, previewing the game with the local media this week, Defence Coach Jonny Bell stressed that, with both teams in the bottom half of the table, they both need the points.
Speaking to the local media this week, Gloucester front rower John Afoa knows the challenge ahead this week against Bristol, and calls on the Cherry and Whites to make the most of home advantage as a determined squad look to bounce back from a narrow loss to Saracens.
Tom Savage speaks to GRTV and the local media as Gloucester went down by 24-20 at Saracens on Sunday afternoon. The second row was disappointed with the result, despite a strong showing from the hosts.
Speaking immediately after the game, skipper Willi Heinz thought that Gloucester had executed their game plan reasonably well and competed hard against Saracens. However, it wasn't enough but the squad will have plenty to work on this week ahead of the derby match against Bristol.
Having named an unchanged starting XV for the past three Aviva Premiership games, Gloucester Rugby ring the changes and retain only five players for Thursday's visit of Stade Rochelais in the European Rugby Challenge Cup (kick off 7:45pm).
