Phil Foden will miss Manchester City's Premier League fixture with Liverpool on Saturday after undergoing surgery for acute appendicitis.
The 22-year-old left the England squad ahead of Sunday's Euro 2024 Qualifier with Ukraine and City said "it is unclear at this stage how long he will be unavailable for."
City, who are looking to chase down Arsenal's eight-point lead at the top of the Premier League, host Liverpool at the Etihad Stadium at 12.30pm on Saturday.
Before the end of April, Pep Guardiola's side also play Bayern Munich twice in the Champions League quarter-finals and take on Sheffield United in the FA Cup semi-finals at Wembley.
According to the NHS, people who have had their appendix removed resume normal activity within two to four weeks. Whether professional football falls under that remains to be seen.
Foden has featured 36 times for City in all competitions this season, scoring 13 goals and registering five assists.
