Leicester City goalkeeper Kasper Schmeichel will undergo surgery after he was ruled out for at least a month with a broken metatarsal.
The Denmark international, 28, suffered the blow in training on Thursday and will have an operation on Friday.
Second-choice keeper Ben Hamer will deputise in their Premier League clash with Manchester City at the weekend.
"An optimistic view for Kasper would be four to six weeks, but it could be longer," said Foxes boss Nigel Pearson.
"It's very unfortunate, clearly the lad is distressed about it and he will be a miss for us but, again, you have to deal with it. We can't change it."
Schmeichel, who signed a new four-year contract with Leicester in the summer, joined the Foxes from Leeds United in June 2011.
