Guy Whittingham and Stuart Gray head to Crystal Palace tonight still unsure whether it will be their last match in charge.
The Selhurst Park fixture represents their fifth game since becoming caretaker managers.
Sean O’Driscoll remains hotly-tipped to take over the Fratton hot seat before the week is out.
Others such as Mark Robins, Chris Coleman and Ole Gunnar Solskjær continue to be linked.
But in a new development yesterday, two national bookmakers stopped taking bets on O’Driscoll.
SkyBet and Stan James closed the book, with the former Bournemouth boss the overwhelming favourite.
Local bookies The Betting Room had already stopped taking bets on Saturday night.
It is widely thought a new man – whoever they may be – will be at the helm for the visit of Forest.
In the meantime, Whittingham and Gray will continue holding the fort.
The first-team coaches have so far overseen two wins and two defeats.
But Whittingham remains in the dark over whether they will soon be handing over the reins.
He said: ‘We don’t know if this is our last game.
‘We haven’t been told whether it is or isn’t.
‘We will just approach tonight as the same as we have done the other ones.
‘We are taking it one game at a time.’
Pompey are currently 18th in the Championship.
That equates to a mere three points off the relegation zone.
Former Blues manager Steve Cotterill will be bringing his Nottingham Forest side to Fratton Park on Saturday.
