Andreas Christensen is unavailable for Chelsea’s game against Leicester on Saturday.
The Danish defender would have been among the substitutes for the match at Stamford Bridge but is recovering from a hamstring problem.
Blues boss Maurizio Sarri says he has been assured that the injury is not serious.
“We have a little problem with Christensen – a little injury to his hamstring,” Sarri explained.
“The doctor told me yesterday that it’s not really very serious but he needs to rest for about a week so we will miss him for a couple of matches I think.”
Sarri added that Christensen is not for sale despite speculation over the player’s future.
Meanwhile, Alvaro Morata has returned to training following a knee problem.
