Preston will wait until January to name boss - Risdale
Preston say they will wait until after the match at Rochdale on 2 January before naming Phil Brown's successor.
North End, who are out of the FA Cup, do not want to rush an appointment.
Chairman Peter Ridsdale told a BBC Radio Lancashire fans' forum: "We'll announce our arrangements by the time of the two-week enforced break.
"During that week we expect to say what will happen for the rest of the season, whether that be a current internal solution or an external solution."
Caretaker bosses David Unsworth and Graham Alexander were in charge for Saturday's and look set to be given at least three more games.
"Having made the change, we've got two very enthusiastic members of our current first-team make-up, who are in jobs that on Saturday had a very good start," added Ridsdale. "We're hoping that start will be built on."
Alexander and Unsworth have been reluctant to discuss their prospects of landing the role full-time and Ridsdale said they have not formally applied for the vacancy.
He continued: "We've had 25 people who have expressed an interest and have a CV worth looking at. We've had some quality applications and we have to get this decision right."
