John Terry has revealed the hamstring injury that will see him miss the start of England's European Championship qualifying campaign dates all the way back to the World Cup.
Chelsea captain Terry will sit out Friday's Wembley opener against Bulgaria as well as the trip to Switzerland four days later after being ordered to rest for the next 10 days.
The defender told Chelsea TV: "I have had a bit of a problem since the World Cup and I was hoping after the World Cup that I would have two weeks off and it would completely go away. But that wasn't the case and, coming back working hard, it came back on."
Terry has played every game for club and country this season but claims the injury was behind his half-time substitution in England's recent friendly win over Hungary.
"I played the last England game but I had to come off at half-time because of it," he said.
"I have not made it public but I have been struggling with it and maybe I just need 10 days' rest to fully get over it because it could impact on my season."
