An MRI scan has revealed what the Crusaders feared after watching the in-form Dagg hobble off Suncorp Stadium during their dramatic 22-20 win over the Reds in Brisbane last weekend.
Dagg, it has been confirmed, will be unavailable for approximately six weeks. He has what is known in medical circles as a PCL and lateral meniscal injury, and a specialist says a small operation is required.
That means the All Blacks fullback/wing is unlikely to be sighted until around the round 10 Super Rugby match against the Cheetahs in Bloemfontein on April 30.
