And then there were four.  Despite falling to their fourth straight loss, Northern Suburbs remained in the hunt to book a spot in a third grand final in four years thanks to Eastwood’s win over Easts.  They face a red hot Sydney Uni side on Saturday. The Students have made one change to their side with former Brumbies utility back James Dargaville replacing Will McDonnell at inside centre.  The Shoreman have made two changes, with Lawrance Hunting returning to the Norths starting side at prop. Lock Connor Vest will miss the preliminary final, forcing a reshuffle in the back five.  Hugh Sinclair will start at lock with Patrick Tafa named at No.8.  Eastwood and Warringah will both take confidence into their preliminary final following impressive wins last weekend.  Woodies winger Kiti Ratu will miss Saturday’s clash and will be replaced by James Sarks, while Hamish Angus returns to the Warringah starting side fresh off winning a third Catchpole Medal this week
