Chiefs' captain Craig Clarke has passed a late fitness test on a knee injury, enabling coach Dave Rennie to name an unchanged lineup for Saturday's Super Rugby final against the Sharks.

Clarke was injured last weekend's semifinal against the Crusaders.

The lock convinced the Chiefs' medical staff today that he was fit to start in the sold-out final.

Rennie has retained the forward pack that stared down the seven-time champion Crusaders and kept a backline which includes Sonny Bill Williams, who will play his last Super 15 match before heading to Japan.

Prop Sona Taumalolo has been retained and, after scoring his ninth try of the season in last weekend's semifinal to become the leading New Zealand tryscorer in the tournament.

Young tighthead prop Ben Tameifuna has also been retained after a strong match against the Crusaders, while Samoa World Cup captain Mahonri Schwalger remains at hooker.

Tanerau Latimer has been confirmed on the openside flank, keeping his young All Blacks understudy Sam Cane among the reserves.

Four current or former All Blacks have been named on the reserves bench: hooker Hika Elliot, Cane, halfback Brendon Leonard and winger Lelia Masaga.

First-five Aaron Cruden will oppose his young Springboks counterpart Patrick Lambie after outplaying his All Blacks' teammate Dan Carter last weekend.

Lambie has overcome an injury and was expected to be named in the Sharks' lineup.

Chiefs: Robbie Robinson, Tim Nanai-Williams, Andrew Horrell, Sonny Bill Williams, Asaeli Tikoirotuma, Aaron Cruden, Tawera Kerr-Barlow, Kane Thompson, Tanerau Latimer, Liam Messam, Brodie Retallick, Craig Clarke (captain), Ben Tameifuna, Mahonri Schwalger, Sona Taumalolo Reserves: Hika Elliot, Ben Afeaki, Michael Fitzgerald, Sam Cane, Brendon Leonard, Jackson Willison, Lelia Masaga
