KEY POINTS:
The in-form Chiefs have made two personnel changes to their starting 15 as they seek a sixth Super 14 rugby win in succession against the Western Force in Perth on Saturday night.
Callum Bruce returns at second five-eighth, where he will be up against 17-year-old James O'Connor.
Bruce began on the bench against the Reds last weekend in his comeback from an ankle injury.
In the other change, loosehead prop Simms Davison comes in, with Ben May switching sides to the tighthead and Ben Castle dropping to the reserves.
At No 8, Sione Lauaki is set to become the 15th player to rack up 50 appearances for the Chiefs.
Coach Ian Foster praised the achievement, saying Lauaki had been an important part of the Chiefs' setup for the past four seasons.
"It is business as usual this week for the Chiefs," Foster said.
"We will continue to focus on improving our game."
