Strap yourself in, as this could be a wild ride.
The Crusaders, currently in second place, have already qualified for the play-offs. However, they need the win, probably with a bonus point, to ensure they have direct passage into the semifinals and enjoy a bye next week.
However, the Highlanders need a comprehensive win over the Crusaders to secure the New Zealand conference trophy and a home play-off match. In short, the Highlanders need to earn five competition points and deny the Crusaders any points.
If the Crusaders and Highlanders are tied on points on the leaderboard, the Crusaders will go ahead because they will have won more matches.
