The Chiefs have made just one change to their line-up for their Super Rugby quarter-final against the Jaguares in Buenos Aires on Saturday (NZT).
Chiefs coach Colin Cooper has promoted Tumua Manu to the starting side in place of Alex Nankivell, who is under an injury cloud and will have to pass a fitness test if he is to play at all.

Nankivell sustained a knee injury during last week's 59-8 win over the Melbourne Rebels, and if he is ruled out, Ataata Moeakiola will take his spot on the bench.
All Black Anton Lienert-Brown will shift from centre to second-five to partner Manu in the Chiefs midfield.
The rest of the team is unchanged, with influential leader Sam Cane captaining the team.
The Chiefs head into the match full of confidence, having won their last three games, including a shock 40-27 win over the Crusaders and a nine-try romp over the Rebels.
"As a team, we need to draw on the confidence we have gained from our past couple of games," said Cooper.
"We are not strangers to quarter-finals rugby, we just need to stay focused, and deliver a performance our fans and whanau are proud of.
"There is plenty of energy in the team, especially from our leaders. We know the Jaguares are a quality side.
"They have performed well and we have the utmost respect for them."
The Chiefs hold the head-to-head advantage over the Jaguares, beating them twice in their three previous meetings, including a 30-27 triumph earlier this season in Argentina.
