The Football Association and Wigan have refused to respond to reports that the club's chairman Dave Whelan has accepted a charge over comments he made about Jewish and Chinese people.
Whelan, 78, had been given until 12 December to answer the FA's punishment.
The governing body has received his response, with some newspapers claiming he has accepted the charge.
Whelan, who warned he would resign as Wigan owner if punished, has denied making racist remarks.
He insisted he was misquoted in a newspaper interview with the Guardian last month, where he was trying to defend the appointment of Malky Mackay as the club's new manager, in which he used the term "chink".
He subsequently apologised for any offence caused.
The FA has also looked into other comments made by Whelan about Chinese people in a December interview with the Jewish Telegraph, in which he said he used to refer to a local Chinese restaurant as "chingalings".
Whelan has received support from singer Sir Elton John, who has been owner of London club Watford on two occasions, 1976-87 and 1997-2002.
Speaking at the unveiling of the 'The Sir Elton John Stand' at Vicarage Road on Saturday - where Watford beat Wigan 2-1 - John said: "Dave Whelan has been a great owner for a fantastic football club with wonderful fans over there, and I salute him."
