Dainton has been part of the Wales squad throughout the autumn internationals and will link up with her new teammates today as they prepare for Saturday’s clash.
John Spencer, President of Barbarian FC, said: “It will be wonderful to see the Barbarian Women back at Twickenham. Hosting the Springboks at the Home of England Rugby is a significant moment in the progress of our women’s side and reinforces our commitment to both the Barbarian Women and women’s rugby more widely.”
