The Highlanders have been hit by two late withdrawals from their team for tonight's game against the Jaguares.
Forwards Liam Squire and Daniel Lienert-Brown are out with sickness and will not be in the reserves.
They have been replaced by Marino Mikaele-Tu'u and Sef Fa'agase.
Tough luck for Squire who was due to come back after not playing all year.
