Stoke boss Mark Hughes has revealed that Jack Butland had a successful operation on his injured ankle and will be in recovery for up to 10 weeks.
The England goalkeeper fractured his right ankle while on international duty against Germany in March, but looked to be nearing full fitness with the Premier League season approaching, only to break down again.
Problems with scar tissue in the ankle meant Butland was withdrawn from selection ahead of the Potters' first game of the new campaign.
"All reports are that the operation went really well," Hughes said at a press conference. "It was a little bit of scar tissue that was restricting movement of his tendon.
"The likelihood is that it will be between six and 10 weeks until we see him."
Reserve keeper Jakob Haugaard is, meanwhile, also struggling with an ankle issue meaning Lee Grant may be in-line to play against Tottenham on Saturday.
"Jakob has had a problem with his ankle which is hindering him from kicking the ball as confidently as he would like," added Hughes.
"We will look at that and if he isn't okay then we have Lee [Grant] here who is more than capable of stepping up."
