Leicester Tigers teammates Handré Pollard and Julián Montoya will meet in the final round of The Rugby Championship to decide the 2024 winner.
South Africa host Argentina in Nelspruit on Saturday (September 28) at 4.00pm (UK time).
If Los Pumas record a second-straight win over the Springboks, after last weekend's win, with a bonus point and deny the home side a losing or try bonus point, they will be crowned champions. Any other result will result in South Africa claiming their fifth title.
The Tigers skipper will captain Argentina against his clubmate, Pollard, who is named on the 'Boks bench.
Elsewhere, in the Test arena, ten of the club's women's squad will feature in the opening round of WXV matches.
