Vincent Kompany could be out for up to four weeks after suffering another calf injury setback, Manchester City manager Manuel Pellegrini confirmed after their 0-0 draw with Leicester City.
Tuesday's match was the first time City have kept a clean sheet this season without the Belgian international in the line-up, but he is set to miss a key run of games in which his side will compete in three different competitions.
"Vincent has an injury, a second degree tear of the calf," Pellegrini said of his captain, who managed fewer than nine minutes as a substitute in the Boxing Day win over Sunderland. "We will see how long he will be out, but I don't think it will be less than three-four weeks.
"I am not a doctor, but with a muscle injury, it will be very difficult for him to be back in less than four weeks.
"But without him, we must continue to defend as we did tonight."
