All Blacks star Brodie Retallick remained in the World Cup frame Sunday after X-rays cleared him of any structural damage to his shoulder injured in the bruising Test against South Africa.

The 28-year-old dislocated his shoulder after being sent flying from a ruck by Springboks replacement forward RG Snyman during the drawn Test in Wellington on Saturday.

Coach Steve Hansen said there was no timeline for Retallick’s return but he was “hopeful he would be available” for the World Cup.

“It’s reasonably positive. He’s only dislocated it. So there is a good possibility he could make the World Cup,” said Hansen.

“He’s one of our best players so we’re relieved. It’s good.”

The All Blacks’ first match in the World Cup is against South Africa on September 21.

The imposing Retallick was a key part of the New Zealand side that won the 2015 World Cup.
