Crusaders inside center, Sonny Bill Williams’s hip injury has prevented him from confronting Hurricanes, Ma’a Nonu on Saturday night.

A scan revealed he had suffered deep bruising and a small muscle tear in the incident that forced him from the field against the Blues.

Last night it was uncertain whether the injury will prevent him starting in the playoffs.

Just looking at the play-off scenario with the last round this weekend, the Reds is the only side that has booked a home play-off spot.

The Stormers and Crusaders are already safe but will need to win this weekend to avoid playing in the first round of play-offs.

Both the Bulls and Sharks face a likely make or break showdown in Pretoria and if the Waratahs win their Australian derby against the ACT Brumbies then they will also be in the play-off.

The Blues will face the Highlanders at 7.35pm on Friday, the Crusaders play the Hurricanes on Saturday at 7.35pm while the Waratahs and Brumbies face each other on Saturday at 9.40pm.
