The Crusaders captain Kieran Read remains in doubt for their Super Rugby clash with the Lions in Johannesburg this weekend.
Read was taken from the field in his 100th Super Rugby game last weekend, a loss to the Hurricanes, because of a head knock.
He travelled to South Africa and assistant coach Aaron Mauger rates him at this stage as just "okay".
Mauger says Read is still showing a few symptons and the team doctor will make a decision in the next 24 hours.
He says Read's ankle injury doesn't appear to be an issue it will be the concussion protocols that will prevent him from being available for selection.
The team will be announced later.
