Hartley out for the rest of the season

England rugby captain Dylan Hartley will miss this year's tour of South Africa and the rest of the Premiership season due to concussion.

The hooker was injured in England's Six Nations match against Ireland last month and has not played since.

"I'm very disappointed that I will not be available for selection for Northampton Saints' remaining Premiership games, as well England's tour to South Africa," Hartley said in a statement.

"It has been recommended by specialists that I take a break this summer and while I find that decision hard to accept, it's important I listen to that advice."

England's three-test series in South Africa starts on June 9.

Hartley suffered a series of concussions two years ago, but returned to lead his country on the tour of Australia in June 2016.

England are already without Bath backs Anthony Watson (Achilles injury) and Jonathan Joseph, who needs surgery on his left foot.

Forwards Courtney Lawes (Northampton Saints) and Nathan Hughes (Wasps) were ruled out in March with knee ligament injuries.

Meanwhile, former England flanker Steffon Armitage has ruptured an Achilles tendon and will be out of action for up to nine months, his French club Pau said.
