The prop is a World Cup winner with 71 Tests behind him and the most-capped player in Super Rugby history after making 202 appearances for the Crusaders.
He leads a starting line-up that includes eight South African internationals and the famous invitation club’s squad includes representatives from eight countries in all.
Chiefs full back Jack Debreczeni — the traditional uncapped player in the starting side — lines up at full back with Tommaso Benvenuti (Italy), Tom English (Australia) and Leon Fukofuka (Tonga) joining three Springboks in the back line.
Crockett, Luke Jones (Australia) and Juan Manuel Leguizamon (Argentina) are part of a formidable forward contingent including South Africa’s captain Siya Kolisi.
The squad was augmented today by the arrival of Cardiff Blues tight head Anton Peikrishvili. The Georgia prop is on the bench instead of France’s Alexandre Menini, who has been recalled by Lyon.
The Barbarians are taking on Argentina for the third time in their 128-year history.
The Pumas were beaten 34-22 at Cardiff 1990 but won the 2015 rematch 49-31. Lood de Jager is the sole survivor from the Baa-baas side that day.
