Canberra Raiders coach Darrin Borthwick's challenged his Green Machine to shut down "world class" Newcastle fullback Tamika Upton.
Borthwick welcomed back his own No.1 weapon, with Canberra custodian Apii Nicholls returning from a foot injury for the top-four NRLW clash at Canberra Stadium on Saturday.
Her fullback battle with Upton will be crucial as the Raiders look to cement their spot in the top eight in their first stand-alone home game since joining the NRLW this season.
