Ederson has been ruled out of Manchester City's top-of-the-table clash with Liverpool on Sunday, Pep Guardiola has confirmed.
The Brazilian goalkeeper was forced off with a thigh injury at half-time of the 1-1 draw with Atalanta and was replaced with Claudio Bravo, who was later sent off.
Defender Kyle Walker ended the night in goal.
"He's not able to play. I don't know when [he will be]," Guardiola told a news conference on Friday.
"We have another top keeper. Claudio Bravo can do it too. We won the Carabao Cup and FA Cup, thanks to Claudio.
