Manchester City boss Manuel Pellegrini has revealed that Samir Nasri could miss up to a month with a groin injury.
The French playmaker missed the midweek Capital One Cup clash with Sheffield Wednesday because of the problem and may now undergo surgery in a bid to address the issue.
Ahead of the weekend's Premier League clash with Hull City, Pellegrini said of Nasri: "It's serious because maybe he will have surgery in the next days. I'm not a doctor but I think he will be out for around one month.
"He was training but he wasn't 100 per cent. He didn't feel comfortable with what he was doing so the doctor decided that was the best option.
"Of course he's a very important player for us and it's not easy for us to play without Samir.
"But I never give excuses about players that, for different reasons, are not in our squad. We have an important squad."
