England captain Dylan Hartley will miss their tour of South Africa as well as the rest of the domestic season with Northampton due to concussion.
Hartley sustained the injury in England's Six Nations 24-15 defeat to Ireland in March and has not featured since.
Following specialist medical advice, Hartley will rest and recuperate over the summer in order to be ready for Saints' pre-season training.
"I'm very disappointed that I will not be available for selection for Saints' remaining Premiership games, as well England's tour to South Africa," Hartley told Northampton Saints' official website.
"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.
"I intend to use this time to recover fully from my injury, so I can be ready to hit the ground running when pre-season training starts later this summer."
