Brad Shields continues to be dogged by injuries in England.

Brad Shields' Six Nations hopes are in tatters with the England loose forward re-injuring the foot that ruled him out of the Rugby World Cup.

Kiwi-born Shields has endured a torrid time at Wasps since heading north and now he looks to be sidelined till the end of January.

England open their Six Nations campaign against France in Paris on February 3 (NZT), leaving Shields little chance of pressing his claims.

Wasps director of rugby Dai Young provided an update on the injury to Shields that came in the recent 9-7 loss to Edinburgh in a European Rugby Challenge Cup match.

"It's a massive blow, unfortunately he just seems to pick up these niggles and can't get a run," Young said of the 28-year-old Shields.

"It's a similar injury but the other side [of the foot]. It's a plantar fascia which is the back of the foot. In the World Cup he did it on the outside, this time he's done it on the inside," Young said.

"It's not quite as bad as it was then … four to six weeks rather than six to eight."

Wasps are again struggling, winning just one of their six English Premiership matches to be 10th in the 12-team championship.

As he works on his rehab Shields posted a touching note he received from a Wasps fan, saying it was providing "a bit of motivation" and that "set backs are a step forward".

Shields abandoned his All Blacks dream in mid-2018, joining Wasps from Wellington and the Hurricanes.

He was instantly selected for England and has played eight tests.

The challenge for Shields is breaking back into an England squad that did so well at the World Cup in Japan, reaching the final against South Africa.

The back row play was one of the English strengths.
