Manchester City talisman Kevin De Bruyne is set to miss Saturday's FA Cup semi-final against Liverpool with an ankle injury.
The Belgian's problem is thought to be an impact injury rather than muscular, but club doctors will have a better grasp of timescales for his absence after more assessment.
Manager Pep Guardiola is likely to be missing both Kyle Walker and De Bruyne, whose performances have peaked as City reach the season's home stretch hunting three trophies.
Guardiola is counting the cost of progressing past Atletico Madrid after Wednesday's tempestuous draw in the Champions League quarter-finals.
