The Crusaders hope to know today if captain Kieran Read can make a return to rugby this weekend against the Reds in Brisbane.
Read hasn't played since suffering a concussion playing against the Chiefs 2 and a half weeks ago.
Crusaders assistant coach Tabai Matson says how Read recovers from training today will be crucial..... however there is no need to rush him back and they'll be cautious, as they are with any head injury.
It is the second concussion Read has suffered this season.
Matson says utility back Tom Taylor, who had to leave the field because of a head knock last weekend will also have to pass a fitness test to be considered for the Reds match.
