Johnson, whose departure from Glasgow Warriors after eight years was announced earlier this month, has been called up along with Japan wing Taichi Takahashi for the game at Twickenham. The initial squads were announced last week and there is a strong Glasgow presence running through both. Johnson will be joined by Warriors forwards Enrique Pieretto and Sione Vailanu in Eddie Jones’ Barbarians side, while Fraser Brown, Allan Dell, Oli Kebble are all in the World XV squad which will be led by Steve Hansen, the former All Blacks coach. Adam Hastings, the Scotland international stand-off and former Glasgow player, is also part of the World XV group along with Edinburgh forward Bill Mata.
Johnson, 29, is leaving Glasgow after making 104 appearances for the club, including 11 this season. The 27-times capped centre was not part of the match-day 23 for last Friday’s European Challenge Cup final against Toulon which the French side won 43-19.
Other notable names in the Barbarians squad include Alun Wyn Jones, the Wales and Lions great who announced his international retirement last week, and Quade Cooper, the Australia legend. Israel Folau is in the World XV squad. The former Wallaby was sacked by Rugby Australia in 2019 following homophobic social media posts. Folau now plays in Japan for Urayasu D-Rocks and has switched international allegiance to Tonga and could face Scotland at the Rugby World Cup in the autumn.
