Reds coach Richard Graham wants recalled centre Ben Tapuai to be more assertive to give the Lions' unfancied backline headaches at Johannes-burg's Ellis Park this weekend.
In the only change to the team who fell 35-20 to Super Rugby frontrunners, the Sharks, Tapuai has regained the centre position from the injured Chris Feauai-Sautia (hamstring).
The seven-test Wallaby had started the season at No13 but failed to make an impact in the 27-17 win over the Brumbies and 32-5 loss to NSW.
Feauai-Sautia immediately took his chance with a two-try display against the Cheetahs and followed up against the Sharks.
Graham expects Tapuai to make the most of his chance tomorrow morning.
