The World Cup starts in just over five weeks, on 20 November, in Qatar.

Fellow England right-backs Kyle Walker and Trent Alexander-Arnold are currently out through injury too.

Manchester City's Walker had groin surgery earlier in October while Liverpool's Alexander-Arnold picked up an ankle injury against Arsenal last weekend.

Walker says he hopes he will be fit in time for the World Cup.

Newcastle's Kieran Trippier is the other strong choice in that position.

Chelsea confirmed that James had received medical treatment from the club and was assessed by a specialist this weekend.

"After consultation between all parties, Reece will now undergo a rehabilitation programme and is expected to be out for eight weeks," a club statement read.

Following their victory at AC Milan, Chelsea manager Graham Potter was asked about players potentially missing the World Cup through injury.

"If anything happens like that, they are going to be disappointed. They are human beings and they want to go," he said.

"They also know it's a profession where things can happen and they are competing at the highest level and you can't avoid this sometimes.

"It's about dealing with the upset and we will help them with that. I can't think of anything from my career that compares with missing the World Cup."

England kick off their World Cup campaign against Iran on 21 November.
