Chelsea goalkeeper Edouard Mendy will miss his side's Carabao Cup tie against Aston Villa but manager Thomas Tuchel says it is "possible" he will be fit to face Manchester City on Saturday.
Villa travel to Stamford Bridge in the third round on Wednesday (19:45 BST).
Mendy missed Sunday's 3-0 league win over Tottenham after picking up a knock against Zenit St Petersburg last week.
"Saturday is possible," Tuchel said of Mendy's chances. "But it's a race against pain and a race against time.
"I hope he will be back in team training on Thursday and if this goes well he can be ready for Saturday, but I don't know right now.
