Chelsea have been handed another injury setback after summer signing Wesley Fofana limped off in a friendly game on Tuesday just days before the return of the Premier League.
Kai Havertz netted a hat-trick as Chelsea beat Brentford 5-1 in a behind-closed-doors friendly but the feat was overshadowed by Fofana limping off with a knee problem.
The Blues will quickly assess Fofana and find out the severity of the injury on Wednesday.
Fofana, who joined Chelsea for £70million from Leicester in the summer, has not played since damaging his knee against AC Milan in October.
Chelsea’s first Premier League match after the restart is at home against Bournemouth on December 27.
