Sky Sports understands that Sunderland have yet to draw up a shortlist of contenders to replace sacked manager Paolo Di Canio.
The Italian was dismissed on Sunday night after Saturday's 3-0 loss at West Brom left Sunderland at the foot of the Premier League table, with just one point from five games.
Kevin Ball has taken temporary charge of the Black Cats, who are back in action on Tuesday night when they will play host to Peterborough in the Capital One Cup.
Sky Sports understands Di Canio arrived at the Academy of Light last night to pack up his belongings and leave but will not get a chance to say goodbye to his players, a lot of whom he brought in over the summer.
News conference cancelled
Reporter Keith Downie added on Sky Sports News: "There had been a news conference scheduled for 1.15 this afternoon ahead of that game but that has been cancelled, so we won't hear from anyone at the club ahead of tomorrow's match.
"Sunderland have a hectic schedule coming up. They are at home to Liverpool on Sunday, then Manchester United visit the Stadium of Light. The Black Cats then go to Swansea before the Tyne-Wear derby at home to Newcastle.
"It would have been hard for Paolo Di Canio to turn things around."
Sky Bet make former Chelsea manager Roberto Di Matteo their 8/11 favourite for the Sunderland job, with Gus Poyet 5/1 and Tony Pulis 6/1.
Sunderland's next Premier League game against Liverpool is live from 3.30pm on Sky Sports 1 this Sunday.
The club confirmed on Sunday evening that they had "parted company" with Di Canio but it is understood that Saturday's 3-0 loss, which saw the Italian face up to angry fans at the whistle, and a subsequent meeting forced Stadium of Light chiefs to act.
A statement on the club's official website read: "Sunderland AFC confirms that it has parted company with head coach Paolo Di Canio this evening.
"Kevin Ball will take charge of the squad ahead of Tuesday night's Capital One Cup game against Peterborough United and an announcement will be made in due course regarding a permanent successor.
"The club would like to place on record its thanks to Paolo and his staff and wishes them well for the future."
Former Sunderland chairman Niall Quinn believes Di Canio's feisty management style may have cost him his job.
Quinn has described the decision as "brave" and told Sky Sports News: "It's a quick decision - some will say too quick.
"They're making a quick decision on this again and looking back, the support Paolo Di Canio got in the summer with the players he brought in, I honestly thought he was going to get longer, no matter the start.
"If we start to peel the layers off in the coming days and find out what life was like under him from various players, you'll probably see a story that says this was a guy who did things in a totally unique way and by the looks of things, the players weren't buying into it.
"They've made a very brave decision to appoint him, they got what they wanted out of him, and now they've made a brave decision (for him) to go.
"It wouldn't have been my style. I think I would probably have tried to give people as much time as possible.
"Something tells me there's a little more to it as well.
"It was perhaps they felt that the players were finding it hard to conform to his unique style. I think that might have played a part in it as well.
"They've made such a brave decision now. Will it pay off for them?"
