Bledisloe Cup 2018: Neck rolls concern star Aussie flanker David Pocock

Wallabies flanker David Pocock has concerns over neck rolls in rugby.

"As a player, you feel that after games and it's not something you want to think too much about," Pocock said when asked about the impact neck rolls would have on his future.

"It's pretty sore,'' Pocock told rugby.com.au after suffering a neck roll from Owen Franks during the first half of Saturday night's 40-12 loss to the All Blacks.

The tackle went unpenalised and left the star flanker so stiff after the game that he had to turn his body to speak to reporters huddled around him. He still had limited movement almost a day after the match.

"I copped a knock and then a bit of a neck roll. It'll be sore but hopefully it's nothing serious."

it's not the first time he has been targeted, reports rugby.com.au.

"There were a few during Super," Pocock said.

"It's something the refs said they were going to really look at.

"There's been some penalties but I haven't watched tonight's game.''

The Wallabies put the issue in front of the citing commissioners in June but opted against doing the same last weekend.

Coach Michael Cheika said there was an onus on his team to try to give Pocock some back-up in that space.

"We have in previous games, in the Irish series definitely," he said.

"He's there nearly all the time, so he becomes a target and they do whatever they can to get rid of him.

"I think today's probably not the day to start going out for that type of stuff but for his own - he could hardly move his neck today.''

Pocock could be heard complaining about the treatment through the referee's microphone throughout the match but post-game he said he had nothing but respect for referee Wayne Barnes.

"The refs are doing their best," he said.

"I thought Wayne was good tonight.

"He's a really good communicator, lets both teams know what he's thinking and you're able to chat to him.''
