Jack Wilshere is not ready to return for West Ham this weekend after suffering a setback in his recovery from ankle surgery.
However, he has not featured since the 1-0 defeat to Wolves on September 1 and needed an operation to fix the "minor issue".
The 26-year-old had been expected to return following the international break, but Manuel Pellegrini confirmed the midfielder remains sidelined.
"Jack felt some pain in the last two days here so he needs more time to recover," the Chilean told a media conference ahead of Saturday's meeting with Tottenham.
There was better news regarding Andy Carroll, though, with the striker back in training following an ankle problem he picked up in pre-season.
"Andy is recovering," Pellegrini added.
"He started this week working as part of the warm-up with the whole squad so we will see in the next week how he improves and I hope that in a maximum 15 days he will at least be working with the squad completely."
West Ham sit 15th in the table, having suffered five defeats from their opening eight matches of the season.
