The Wanganui High School 1st XV has slipped to third on the Manawatu McDonalds Colts division rugby championship table after a 27-13 loss to reigning champions Massey White at the weekend.
The other Wanganui side, St Johns Club Metro, now sits second on points behind the unbeaten Massey White.
The Wanganui derby clash between WHS and Metro this Saturday will determine the semi-final match-ups the following week.
However, the most likely scenario is a semi-final between Metro and WHS with championship leaders Massey White playing likely fourth-placed Old Boys Marist Colts.
On paper at least WHS would have to be favourites against Metro this weekend after beating the division debutants earlier in round robin play.
