Jack Wilshere has suffered another injury setback with the West Ham midfielder unlikely to return until November.
The 26-year-old, who joined West Ham on a free transfer in the summer, underwent a minor operation in September after sustaining the injury against Wolves, and was expected to be sidelined for around six weeks.
However, Wilshere is still having to rest due to some inflammation around the ankle meaning he is unable to resume training, pushing his likely return date back until next month.
Manager Manuel Pellegrini said: "Jack felt some pain the last two days here so he needs more time to recover."
The Argentine also revealed how Andy Carroll was back training on the pitch, with the striker yet to feature this season after suffering a recurrence of an ankle problem during pre-season.
"Andy is recovering," added Pellegrini. "He started working this week, part of the warm-up with the whole squad, so we will see in the next week how he improves.
"I hope that in a maximum of 15 days he will at least be working with the squad completely."
Pellegrini also confirmed forward Marko Arnautovic will be fit to face Tottenham on Saturday despite an ongoing knee problem.
