New Zealand international Brodie Retallick will continue to remain on the sidelines for another three weeks after failing to make sufficient recovery from a wrist injury.
The 27-year-old has been out of action since 13th April when he suffered the blow while playing for Chiefs in the Super Rugby encounter against Blues.
He was initially expected to return to action this weekend when Chiefs play Highlanders but head coach Colin Cooper provided an update on the 6ft 8in lock.
"Brodie's probably another three weeks away, so we're looking at probably the Reds," said Cooper.
Chiefs have already lost the services of full-back Damian McCkenzie for the remainder of the season following a knee ligament injury while Sam Cane is recovering from a broken neck.
Chiefs currently are languishing at the bottom of the New Zealand Conference with three victories from 10 games this season.
