The Bourgoin scrum half, a replacement against Scotland and Ireland and a starter against England despite being eight months short of his 20th birthday, leads a powerful Les Bleus managed by French legend Philippe Sella.
Parra played in all six of Bourgoin’s Heineken Cup matches this season, including their clashes with the Ospreys, and is joined in the French U20 team by Stade Français Paris centre Mathieu Bastareaud.
Bastareaud played in two Heineken Cup matches for Stade this season, including their match against Cardiff Blues at the Arms Park.
Wales, who have won their last three matches after losing to England on the opening weekend, are in second place in the U20 Six Nations table with France, who have also recorded three wins, third on points difference.
Wales and France will face each other again on June 14th at the Liberty Stadium in Pool D of the inaugural IRB Junior World Championship being staged by Wales.
