Northampton expect Hartley return this season
Dylan Hartley is expected to return to action for Northampton Saints before the end of the season.
The hooker missed all of England's Six Nations campaign because of a knee injury that has kept him out since December.
But Northampton are confident of the England captain getting some game time for his club ahead of the World Cup in Japan.
"Dylan has been to the specialist. It was really positive," Northampton's director of rugby Chris Boyd said after Friday's win over Leicester Tigers.
"I'm not sure when, but I'm really optimistic Dylan will play some football before the end of the season.
"He might be three to six weeks, but he's in a really good space."
England face the Barbarians on June 2 and play four further warm-up games before their World Cup opener against Tonga on September 22.
