Chelsea midfielder Romeo Lavia is set for a further spell on the sidelines.
The Blues have been rocked by news that their summer signing from Southampton may not feature for many weeks.
The 19-year-old could be set to miss until mid-October as his ankle has a muscle tear.
Lavia sustained the injury in training during the international break, as he was building up fitness after missing preseason.
Manager Mauricio Pochettino is also without record signing Moises Caicedo at present.
The Ecuadorian sustained a knock while on international duty for his nation's World Cup Qualifiers.
