Chelsea defender Ben Chilwell will be out for at least six weeks with a knee injury but the Blues hope he will not need surgery.
The 24-year-old England left-back suffered the problem in Tuesday’s 4-0 Champions League win against Juventus.
“Ben has a partial injury of his ACL,” said Chelsea boss Thomas Tuchel.
“The next six weeks will tell the story actually if he makes it and if he will be fully available after the six weeks, or if he needs surgery after that.”
He added: “Right now I only care about the six weeks. We are very positive because the first reaction of his body is very positive.
“Hopefully it stays like this so now the full focus of everybody is on the next six weeks, to try to bring him back to play.”
Chilwell has been in impressive form, with three goals and one assist for the Blues this season.
