Sergio Aguero will miss Manchester City's home clash with Cardiff on Wednesday night, boss Pep Guardiola has confirmed.
The Argentinian striker went off against Fulham on Saturday through injury and has not yet trained this week.
Guardiola said at a press conference previewing the game: "He didn't train the last two days. Tomorrow he is not able.
"Hopefully next Saturday, next Wednesday. We will see his evolution in the next few days."
Guardiola claims City will treat the Cardiff clash as a cup final and is wary of the threat posed by the Welsh club, who suffered a controversial late defeat to Chelsea on Sunday.
"They are not a team that is already done," he said. "They have spirit and what they do, they do well.
"We know how we are going to play. For us it is a final - every single game."
Fabian Delph also remains sidelined but Benjamin Mendy could feature.
Guardiola added: "Sergio and Fabian Delph are out but the other ones are OK."
