Chelsea believe they'll be missing Romelu Lukaku for the next five games.
Lukaku damaged his ankle in Chelsea's Champions League victory over Malmo in midweek at Stamford Bridge.
The Times says Lukaku isn't expected to be back in action until after the next international break in November.
As such, the striker is set to miss at least the next five Blues games.
Tim Werner also suffered a hamstring strain during the 4-0 defeat of Malmo.
