Bok pivot Pollard ruled out of Rugby Championship: 'He's a bit of a worry,' says Rassie

Handre Pollard has now emerged as the Springboks' biggest injury headache ahead of the World Cup title defence in France.

Rassie Erasmus, the national director of rugby, on Tuesday revealed that the trusty pivot will in all likelihood not feature in the upcoming Rugby Championship at all, contrary to some initial optimism.

This latest development renders the decision to recall Elton Jantjies even more prudent, despite Erasmus also confirming that Stormers stalwart Damian Willemse is "all ready to go".

Manie Libbok is the other flyhalf in the squad.

"When you only have two flyhalves in your group, you tend to put undue pressure on the guy who's injured.

"Elton's presence, especially, helps us at
