Emma Hayes will take a step away from her job as Chelsea Women manager to recover after undergoing an emergency hysterectomy.
Hayes, 45, revealed she had surgery last week as part of her ongoing battle with endometriosis.
In a statement, Hayes said she would “need time and patience to return to full health”.
Assistant manager Denise Reddy will take caretaker charge, with general manager Paul Green carrying out media duties.
A club statement said: “Everybody at Chelsea would like to wish Emma a speedy recovery and we will continue to support her during this time.”
