Burger, a veteran of 68 Tests, almost had his career ended a few years back after serious neck and back surgery and last weekend at Newlands fears erupted that the injury had resurfaced.
He took a knock to his neck early in the match against the Cheetahs and appeared in great discomfort, forcing him to miss the second half.
“I was in a bit of a grapple for the ball and then Coenie Oosthuizen landed on me and I felt a bit of a spasm afterwards,” said Burger.
Burger is however in doubt for the Super Rugby clash against the Sharks in Durban this weekend and has only been given a 50/50 chance to play, while wing Kobus van Wyk has been ruled out of the clash due a recurrence of his wrist injury.
Making his return to the Bok fold for the first time since 2011, Burger said he was thrilled to be part of the current national training camp.
“I am picking up niggles here and there, but I’ll be okay and I was thrilled to join the Springboks on Sunday.
“I’m actually quite excited about it,” Burger said of the training camp in Durban.
The flanker said he was over the moon with the Stormers performance against the Cheetahs which had raised a lot of hype for this weekend’s clash against the red-hot Sharks.
“We played the conditions better than they did and when you get a headstart in this type of weather, the momentum can stay with you,” Burger explained.
“We made the right decisions and we took our opportunities well.”
But there is a big injury concern in the Stormers camp with hooker Deon Fourie leaving proceedings with concussion.
