Chelsea defender Ben Chilwell could be a huge doubt for the World Cup after he limped off in the final moments of Chelsea's Champions League match against Dinamo Zagreb.
Chilwell pulled up clutching his hamstring in the fourth minute of added time before he was helped off the field by the Blues medical staff after the full-time whistle.
The 25-year-old had just recently recovered from a long-term knee injury but could now miss more action including England's World Cup campaign with another injury.
