Manchester City were dealt a major blow on Monday with leading scorer Erling Haaland set for a spell on the sidelines after suffering an ankle injury as the season reaches its climax.
The 24-year-old Norwegian was injured in Sunday's 2-1 FA Cup quarter-final win at Bournemouth.
Having just scored his 30th goal of the season to level the tie, he was then hurt in a challenge with Bournemouth midfielder Lewis Cook.
The Premier League champions did not provide a timescale for the player's return.
"The expectation is that Erling will be fit in time to play a further part in the remainder of this season, including this summer's FIFA Club World Cup," said a club statement.
"Erling underwent initial tests in Manchester on Monday morning and will now seek specialist consultation to confirm the full extent of the injury.
"Assessment remains ongoing to ascertain a full prognosis."
City are currently fifth in the Premier League and battling to ensure a spot in the Champions League next season.
Pep Guardiola's side face matches against Leicester and Manchester United this week.
They then have a visit from Crystal Palace and a trip to Everton before their FA Cup semi-final against Nottingham Forest, at Wembley on April 26.
Erling Haaland will be out of action for up to seven weeks after suffering an ankle injury, Manchester City manager Pep Guardiola said.
Guardiola gave an update on Tuesday, on the eve of his side's Premier League match against struggling Leicester at the Etihad.
"The doctors told me between five and seven weeks," he said. "So hopefully for the end of season and FIFA Club World Cup he will be ready.
"Sometimes there are years where these kinds of things happen. It's happened all season."
Guardiola said City did not have another player with Haaland's attributes but would have to adapt as they chase a spot in the Champions League next season.
City are currently fifth in the Premier League, which is likely to be enough to secure a place in Europe's top club competition after strong performances from English clubs in European competition.
They have nine games left in the Premier League season plus an FA Cup semi-final against Nottingham Forest towards the end of April.
