Force's tall timber ready for Jaguares attack
Loosehead prop Francois van Wyk moves into the starting jumper for the first time this season, while captain Heath Tessmann has his fourth start of the season at hooker.
It's taken over 18 months, but finally for the first time we will see Adam Coleman and Richie Arnold starting in the second row together, combining to be one of the tallest lock combinations in Super Rugby.
Ross Haylett-Petty moves to the blindside flank position, Force Foundation member Onehunga Havili will make his run-on debut at openside flank and Richard Hardwick rounds out the forward pack changes in the No.8 jersey.
Changes in the backline see Semisi Masirewa come in for his first game of the season and veteran Peter Grant slots into fullback for his first start of 2017.
Anaru Rangi is the only new face on the bench, as the big New Zealander is set to come on for his second match of the season at reserve hooker.
