Bradford head coach Mick Potter will return to Australia after Friday's match against Hull KR unless there is a positive end to the uncertainty over the future of the beleaguered Bulls by then.
Potter and his assistants Francis Cummins and Lee St Hilaire have been working without pay since they were made redundant by joint administrator Brendan Guilfoyle five weeks ago and the Australian has kept putting off a final decision on his own future.
But his patience is running out and he has delivered a final ultimatum, telling a media briefing: "The situation needs to be resolved because it's an on-going joke now."
The Rugby Football League rejected a bid from a consortium of local Asian businessmen after labelling it "unsatisfactory" and Super League bosses stepped into the long-running saga last Thursday with an offer to buy Bradford on behalf of the other 13 clubs in an effort to break the deadlock.
Super League (Europe) are still waiting for Guilfoyle's response to their offer and Potter says time is fast running out for him.
"I need an answer this week," he said. "I thought there was going to be something today but tomorrow will be fine as long as the answer is in the positive.
"Otherwise I'll just go back home. If Guilfoyle turns it down and I don't get paid, I'll just go home. I've looked at flights."
Potter, whose wife Megan was also among the 16 full-time members of staff laid off, has not turned to the hardship fund set up by fans to help those made redundant.
