Ref Mark Clattenburg has turned down the chance to officiate in the Premier League this weekend.
The Daily Mail says Clattenburg has decided not to referee a match for a second weekend running as he prepares to answer accusations from Chelsea.
Mike Riley, general manager of Professional Game Match Officials Limited, said: "PGMOL was fully prepared to appoint Mark to matches this weekend. However, having discussed this with him, we both consider that it is in Mark's best interests that he has this week away from officiating duties while he prepares to help the FA and police with their enquiries."
