I'd totally forgotten Scotland were were at this RWC. Probably best they stay under the radar.
Four changes from the game against SA. Harris and Steyn in for Jones and Graham suggests a more defensive minded approach for the first 40-60 given Tonga's physicality and the fact that it's a must not lose game for both sides. Horne, Jones and Graham off the bench when things open up more in the second half and tries are needed for the BP.
Scotland: B Kinghorn; K Steyn, C Harris, S Tuipulotu, D van der Merwe; F Russell, B White; R Sutherland, G Turner, Z Fagerson, R Gray, S Cummings, J Ritchie, R Darge, J Dempsey.
Replacements: E Ashman, P Schoeman, W Nel, S Skinner, M Fagerson, G Horne, H Jones, D Graham.
