The Hurricanes captain and All Blacks number eight Rodney So'oialo is rated only a 50-50 chance of playing in Saturday night's Super 14 semi final against the Crusaders in Christchurch.
So'oialo suffered a rib injury in Friday night's loss to the Blues and coach Colin Cooper says they'll have to wait until later in the week before making a decision on So'oialo's fitness.
The Crusaders number eight Mose Tuiali'i is also in doubt for the match having suffered a knee injury in the Crusaders surprise loss to the Highlanders on Saturday night.
