Cardiff City assistant manager David Kerslake faced the media in a tense press conference this morning, standing in for Malky Mackay who was due to appear.
He repeatedly refused to answer questions about Mackay's future, revealing only "Malky is in the pavilion" [at the training ground], and, when asked if Mackay will still be in charge tomorrow against Liverpool, "nobody has said anything different to me."
Cardiff City assistant manager Kerslake said at this morning's press conference: "I am here to talk about the Liverpool match, I came in this morning and was asked to do the press conference.
"Malky is in the training pavilion as we speak, we are just here to talk about the game."
When asked if Mackay was still in charge, Kerslake answered: "No one has said any different to me, everything has been as normal. Players have got on with their jobs. Without being boring it has been a normal week."
A club spokesman later stepped in to say: "Malky Mackay is unavailable to speak to the media, the assistant manager is here."
When faced with further queries on Mackay, Kerslake said: "I will answer any questions you have about the game of football tomorrow."
I was at a very tense press conference this morning at the Vale Resort.
Malky Mackay was expected to speak to the media, but, at late notice, that was changed to his assistant manger David Kerslake.
Kerslake was repeatedly asked about Mackay's position, and the uncertainty at the club, but refused to answer any of those questions, wanting to focus solely on tomorrow's game at Liverpool.
Kerslake did say Mackay is in the training centre this morning, and due to take training.
As of this morning, Mackay is still the club's manager, and preparations continue for tomorrow's game.
Cardiff City have said Malaysian owner Vincent Tan is expected to fly into the UK later today.

The situation at Cardiff City dominates the sports pages of today's Welsh - and London - newspapers, with the message 'resign or be sacked' prominent.
The Sun reads 'Now Get Out' and says Mackay expects to be removed from his post on Monday, after Cardiff's game against Liverpool tomorrow.
The Telegraph says it will cost Cardiff owner Vincent Tan £3.5m to sack Mackay under the terms of his contract.
The Western Mail says former Cardiff manager Dave Jones is poised to return to the club as a potential director of football, if - or when - Mackay leaves.
The Times describes Cardiff as a club 'in turmoil.'
Mackay is due to speak at his weekly press conference in the next few minutes - we will have updates.
The future of Cardiff City manager Malky Mackay has been cast into major doubt this evening after the club refused to deny reports that he has been told to resign or be sacked from his post by owner Vincent Tan.
A Cardiff City spokesperson said that the club would not be involved in any letters exchanged between the two individuals.
Mackay's post has been under threat for several weeks since his relationship with the Bluebirds billionaire backer seemingly deteriorated over the decision to dismiss Mackay's head of recruitment and friend, Iain Moody, a move Tan later revealed was due to a summer overspend of £15m.
Earlier this week Tan again piled pressure on Mackay's post by issuing a statement through club Chief Executive Simon Lim.
The statement read:
"Tan Sri Vincent Tan was extremely upset to read quotes from the manager concerning the possibility of new recruits, before he had been informed whether funds would be made available."
"He believes that doing so unfairly raises supporter expectations, placing unnecessary pressure on the club."
"His view is that due to the funds already committed, including the originally authorised summer transfer budget of £35m that rose to £50m in total, including add-ons, the manager has been fully supported."
"The overspending of £15m has upset Tan Sri greatly, resulting in the removal on Iain Moody as head of recruitment. As such, he has stated that not a single penny will be made available in January."
"Having been the highest-spending promoted club and the seventh-highest spender in the Premier League last summer, the owner believes that the manager has been given the best possible chance of retaining our Premier League status."
Liverpool Manager Brendan Rodgers, a former adversary of Mackay's during his time in charge of Swansea City, has jumped to the Scot's defence over the situation.
Former Swansea City manager Brendan Rodgers has come to the defence of Cardiff counterpart Malky Mackay, and claimed the capital club's owner Vincent Tan "knows nothing about football."
Rodgers, now in charge of Liverpool, was responding to questions on the fall-out at Cardiff, after Malaysian owner Tan said he was "extremely upset" at comments Mackay made about transfer funds.
"I find it astonishing what he has had to go through", Rodgers said.
"He has had great results this season and is going to go on and be a great manager at a big club and I find it absolutely astonishing there is talk about him leaving there."
"My only conclusion is you have a business guy operating the club who knows absolutely nothing about football.
"He has obviously been a successful businessman - congratulations but football is like no other business."
"When I see what Malky has had to put up with, to see him being questioned I find it remarkable.
"Especially when supporters there look up to him and respect him for what he's done."
Cardiff City manager Malky Mackay has spoken publicly for the first time since his future was cast into doubt, after the departure of his close freind and head of recruitment Iain Moody.
Mackay apologised to fans for what he called a "disappointing" time - and he went on to say that he was never asked to leave club, or considered doing so.
