Sacked Bradford coach Mick Potter claims Brian Noble is set to return to Odsal.
Potter was among 16 staff made redundant in a major cost-cutting exercise by administrator Brendan Guilfoyle, who is attempting to keep the troubled Bulls afloat during his search for a buyer.
Australian Potter turned down an offer to continue his job as head coach in an unpaid capacity, but Guilfoyle says he has received several offers to coach the team on a voluntary basis ahead of Sunday's home game against London Broncos.
Potter claims the club have lined up Noble, who guided the Bulls to five consecutive Grand Finals under former chairman Chris Caisley before moving to Wigan in 2006.
Potter also reveals Noble offered assistant coach Francis Cummins his job back but the former Leeds winger declined.
"There are things going on that aren't what they appear," said Potter, who intends to return to Australia to find a job.
"It's very early in the piece for Brian Noble to come on board, given that they've just sacked all the staff. It's pretty ordinary really.
"But Francis, to his credit, has held onto his honour and I take my hat off to him."
Noble, who was Great Britain coach from 2004-06, has been out of coaching since leaving Crusaders at the end of 2010, although he had a brief spell as a consultant to Halifax last year.
Guilfoyle refused to confirm rumours that Noble had been earmarked for a return.
Potter, meanwhile, says he felt as if he had been "stabbed in the front" by the club and the Bulls players last night issued a statement expressing their dissatisfaction through the Super League players' association, 1eague3.
"We are deeply sympathetic towards the staff and coaches who have paid the ultimate price in these terrible circumstances," they said.
"We are forever thankful for the help and guidance we have all received from each and every one of them and would like to wish nothing but the best for their future endeavours.
"The players have been kept in the dark about the current situation for some considerable period of time.
"We received precious little information from the club prior to administration and we were only told that the club had entered administration on the day it happened.
"Now that the club has entered administration, we have still been kept in the dark and starved of information. We do not know whether this weekend's game will go ahead.
"It is apparent that information was provided on a 'need-to-know' basis and it was considered that the players did not need to know.
"We simply do not know whether we will have a job next week, let alone whether we will play on Sunday."
The players will be pressing the administrator for answers at a meeting on Tuesday morning.
