Canberra Raiders coach Ricky Stuart has made mass changes to his side in an attempt to get the Green Machine back on track, dropping Curtis Scott and tinkering with his back line. Scott has been moved from right centre to the interchange bench, Jordan Rapana has been ruled out with a calf injury and Joe Tapine returns to replace Corey Horsburgh. Stuart revealed Horsburgh could miss the entire season after having scans on a foot injury this week. In other changes, Nick Cotric will move to the left wing, Bailey Simonsson is on the right wing and Michael Oldfield gets his opportunity at right centre. The right edge has been one of the Raiders' biggest issues since the NRL restart in May, with Cotric and Scott failing to strike a dangerous combination.
