The Chiefs need to restore their conviction and systems after being flogged last round by the Crusaders.
The playoffs start next week and the Chiefs need to recover the menacing accuracy that was so evident before the Super 15 broke for the June test window.
Liam Messam returns from injury to lead his men with a change of impact expected from fellow forwards Tanerau Latimer and Toby Smith and new backs Andrew Horrell, Robbie Robinson, Lelia Masaga and Tim Nanai-Williams.
A head knock took Sam Cane out of starting consideration while Ben Afeaki damaged his back at training so Ben Tameifuna kept his place.
Coach Dave Rennie was keen to get Horrell back into the mix and switching Robinson to the wing gave the Chiefs extra kicking variety without any loss of speed. He put the heat on Bundee Ah Kee and Tawera Kerr-Barlow after last week.
Kirwan and his squad have been trying to get themselves sorted after two disappointing defeats in Africa. It had been a tough last section of the tournament and they were upset they had not made the playoffs.
"Yeah, we would have all loved to have made the playoffs, but it hasn't happened," Kirwan said. "But we've played some great football and are heading in the right direction, so we need to go out and play for pride and show people we are a force to be reckoned with."
No8 Peter Saili was still troubled by flu yesterday but the staff think he will be fine to suit up tonight.
The Blues have chosen 35 players, including tonight's debut for left wing Lolagi Visinia this season in a campaign that stands at six wins and nine defeats. Better than the four wins and 12 defeats last year, but there is still a long way to go.
Victory tonight would arrest the five-game slump and leave the Blues with more optimism for 2014.
