Libbok shoots up Bok flyhalf queue as niggles thrust Elton Jantjies back into selection frame

Niggles to the Springboks' main flyhalves have surged Stormers pivot Manie Libbok to the top of the pivot pile for the Rugby Championships, while Elton Jantjies remains in the selection frame.

First-choice flyhalf Handre Pollard missed his club Leicester Tigers' Premiership semi-final against the Sale Sharks with a lower leg injury.

The Tigers ended up losing that game, with Pollard suffering a lower leg/calf injury that SA Rugby director of rugby Rassie Erasmus says has taken a bit more time to heal than expected.

"Handre's got a calf problem again and it's taken a little bit longer to heal," Erasmus said.

"Initially, we thought he'd be back in the next week, but he'll definitely be part of the Rugby Championship.

"To add to that, Damian Willemse also has a knock to his knee ... Manie is now the only one who is 100 percent fit and running, but we know that with the other two, they'll be fine.
