Both missed last week with niggling injuries, although the squad still has 12 players unable to be considered for selection.
Coach Tana Umaga said he is looking for a significant improvement in their team defence and discipline for the repeat game against the Chiefs, after last week's loss to the Sharks.
"We let ourselves down with our team defence. The boys all realise that and have come in this week with a determined attitude. Last year we were developing into a strong team defensive unit and we must get back to that level.
