Lions rush their Bok back
The Lions take on the Eastern Province Kings in Port Elizabeth on Saturday.
Mostert, who has been training with the Boks since the start of he international season, is one of tree players released by the Boks.
He will resume his second row partnership with veteran Martin Muller.
The starting XV – which shows 10 changes from that which featured in the last match in Super Rugby – has a healthy influx of youth.
The most noticeable absentees are Elton Jantjies (on Springbok duty), Francois de Klerk (back to the Pumas), Warren Whiteley (on Bok duty), Warwick Tecklenburg (Japan), Armand van der Merwe and Schalk van der Merwe (both France).
While those players are all set to return for Super Rugby next year, Ackermann is busy unveiling the next generation of Lions in the Currie Cup.
