Chelsea and England defender Ben Chilwell is expected to miss the World Cup with a "significant" hamstring injury.
The 25-year-old left-back sustained the problem in the Blues' 2-1 Champions League win over Dinamo Zagreb on Wednesday.
A statement from the club on Saturday said: "Following the injury sustained in our recent game against Dinamo Zagreb, Ben has undergone a scan on his hamstring.
"Results show that Ben has suffered a significant injury and the defender is unfortunately expected to miss the World Cup.
"Ben will now begin a rehabilitation programme with the club's medical department."
