Manchester City defender Aymeric Laporte will be out until January or February, says manager Pep Guardiola.
The France centre-back, 25, has had surgery on his right knee after being carried off in the 4-0 win over Brighton on 31 August.
He damaged his cartilage and lateral meniscus in a challenge with Brighton defender Adam Webster.
On Laporte’s absence, Guardiola said:
“Not long. Five months, six months – next year, January or February.”
The defender made 35 league appearances last season, with Bernardo Silva the only City outfield player to play more.
His injury leaves City with just Nicolas Otamendi and John Stones as central defenders, following the departure of Vincent Kompany to become player-manager of Anderlecht in the summer.
Stones could play at Norwich City on Saturday in the 17:30 BST kick-off and Guardiola said the England centre-back “trained good”.
