The Football Association has granted David Moyes a further week to respond to his charge in relation to comments made to a female reporter after Sunderland's meeting with Burnley in March.
Moyes told the BBC's Vicki Sparks that she might "get a slap" following a post-match interview, a remark which the FA alleged was "improper and/or threatening and/or brought the game into disrepute".
The under-fire Black Cats boss initially had until 6pm on Wednesday to respond but has now been given seven more days by the governing body.
Moyes could face a two-match touchline ban if he admits the charge, as well as a fine, should the FA deem that the comments were of a threatening nature.
Reports overnight suggest that Sunderland may part company with the Scotsman, whose first season at the Stadium of Light helm will end in relegation.
