Cape Town - Springbok centre Jesse Kriel is an injury worry ahead of the second Test against France in Durban on Saturday.
Kriel was substituted in the 57th minute of this past Saturday's 37-14 victory over the same opposition at Loftus after he came off second best in a heavy collision with his opposite number, Henry Chavancy.
A groggy Kriel did not return to the field and his place was taken by Bok veteran Frans Steyn, who moved to No 12 while Jan Serfontein shifted outside to No 13.
The Boks will be hosting a press conference on Monday afternoon and they are expected to file a full injury report then, but if Kriel is ruled out then Bok coach Allister Coetzee has limited options.
Starting with Steyn at 12 and Serfontein at 13 is the likeliest alternative, but Coetzee might also have Lions centre Lionel Mapoe available after he recovered from a knock last week.
The fitness of Damian de Allende could also have an impact, while Cheetahs skipper Francois Venter is currently with the SA 'A' side.
Both Kriel and Serfontein scored tries for the Boks on Saturday.
