Manchester City are hopeful the injury which sidelined Erling Haaland at the weekend is not serious.
The Norway striker missed City's 1-0 Premier League victory at Leeds on Saturday with an unspecified problem sustained in training prior to the game.
Manager Pep Guardiola did not give a clear indication of when the 25-year-old might return but it is understood the issue is not a major concern.
Haaland, who has scored 29 goals in all competitions this season, will be assessed on Monday and Tuesday ahead of Wednesday’s clash with Nottingham Forest at the Etihad Stadium.
"I don’t have an answer right now," said Guardiola after the game at Elland Road. "He was not ready for today but we have four days before Nottingham Forest and after, three days to the FA Cup at Newcastle at 8pm."
He then made a pointed swipe about the kick-off time for next Saturday’s fifth-round tie at St James’ Park.
"Thank you so much for that time, to go better to Madrid with less recovery, thank you," said Guardiola.
Nico O’Reilly, who was withdrawn after 70 minutes at Leeds with an ankle injury, will also be checked.
