Maurizio Sarri does not believe his defender Toni Rudiger is seriously injured.

Rudiger came off during the second half in the 0-0 draw between Chelsea and West Ham United.

But his Chelsea boss does not think that it is a serious or long term injury.

"I don't know," said Sarri on the injury to the Chelsea official website.

"I want to speak with the doctor. I think nothing serious, maybe three or four days, no more."
