Kevin De Bruyne will miss Manchester City's game against Bournemouth on Saturday and is doubtful for the clash with Chelsea on December 8.
Sources have told Goal that De Bruyne is not yet back in training with the City squad and is definitely out of the meeting with the Cherries.
The trip to Watford on Tuesday had been regarded as a possible return date, although given the Belgian's lack of training that is currently considered unlikely.
If he is not able to play at Vicarage Road then it would make the chances of a return to the starting line-up at Chelsea very slim.
