There are two changes in the forwards this week, with George Bower joining the starting side, and Isileli Tu'ungafasi providing cover at loosehead prop on the bench. Joe Moody will not travel to Hamilton with the side due to a family bereavement.
Flanker Sione Havili joins the starting side in the number six jersey, with Tom Sanders shifting to Number 8 in place of Whetukamokamo Douglas, who is recovering from a medial ligament injury.
There is just one further change in the backline this week, with Mitchell Drummond earning a start, and Bryn Hall named on the bench. Fetuli Paea will once again line up in the midfield alongside Jack Goodhue, with Braydon Ennor still recovering from the toe injury he sustained in the Blues game.
Robertson said: "First and foremost, the thoughts of the Crusaders team and our wider organisation are with Joe Moody and his family at this very sad time, and we'll certainly be thinking of them when we take the field on Saturday night.
"As a group, we're also really proud to be celebrating Sam's 150-game milestone this week, he is such a quality leader and a massive contributor to our team. He's a proud Crusader, and I know the side is keen to show him plenty of respect with our performance.
"We had a really honest review following the Hurricanes game, and identified areas we need to get better this week. We're coming up against a Chiefs side who have only been beaten by the smallest of margins so far in this competition, and will be desperate for a win in front of their home fans."
Kick off in the Crusaders match against the Chiefs is 7:05pm, Saturday 1 August at FMG Stadium in Hamilton. The match will be televised live on Sky Sport.
