Bernardo Silva has been given more time to respond to a Football Association misconduct charge.
The deadline for a response was originally set for Wednesday, but it is understood that has now been extended to October 21.
The 25-year-old is possible to face a six-match ban for comparing his teammate with Spanish chocolate-covered peanut named Conguitos.
"Bernardo is one of the most lovely people I have ever met in my life," Guardiola said on September 25.
"He speaks four or five languages - that is the best way to understand how open-minded he is - and one of his best friends is Mendy. He is like a brother to him. The image for the two is not about the colour of the skin."
