It's not as bad as first thought and he could come back in a few weeks.
After scoring his first Blues goal, Fofana injured his ankle.
Scans show he avoided serious damage after leaving the stadium on crutches.
It is not as bad as we thought. Manager Graham Potter said after the game that they were worried.
We believe it will be a few weeks. It's much better than it could be.
Potter said that it was possible that he could return before the World Cup starts. There is a chance, but we wouldn't want to put too much of a time scale on it.
Potter stressed that the club would not take any risks with N'Golo Kante.
Kante was injured in the 2-2 draw against Spurs in August.
N'Golo is getting more and more involved with the team. Potter said that he was not available for the weekend but that he was getting closer.
