South Africa have included experienced lock Lood de Jager in their squad for their decisive Rugby Championship match against Argentina at Twickenham on Saturday after Franco Mostert did not travel with the group due to a family bereavement.
De Jager was injured in the record 43-10 victory over New Zealand in Wellington this month, but has been passed fit to play. Coach Rassie Erasmus will name his team on Tuesday.
"We all feel deeply for Franco and wish him strength during this challenging time, and we’ll support him as well as we can," Erasmus said.
"Fortunately, Lood has recovered from his injury, and his experience and leadership will be valuable in such an important week for the team."
