The English Football League has said it cannot make progress with Massimo Cellino's bid to purchase Leeds as it has yet to receive "all of the information it has requested for the relevant parties".
In another twist to what has become a farcical saga at the Championship club, the League added that the transfer of one of Cellino's players, Andrea Tabanelli, could not be approved because it did not comply with its regulations.
"At its meeting on Thursday, the board of directors of the Football League were appraised of the current situation regarding the ownership of Leeds United," the statement read.
"The board were informed that the League is yet to receive all of the information it has requested from the relevant parties.
"The matter cannot be progressed further until the required information is forthcoming.
"Separately, Leeds United have been informed that the Football League has refused the registration of Andrea Tabanelli as the transfer did not comply with League regulations."
The League's statement came a week on from the outbreak of controversy at Elland Road, after Cagliari owner Cellino flew into Yorkshire and agreed a 75 per cent purchase of Leeds from the club's current owners, Gulf Finance House Capital (GFH Capital).
The 57-year-old agricultural entrepreneur then oversaw a number of extraordinary events, including the unauthorised sacking and reinstating of manager Brian McDermott, while also triggering a boardroom row over the club's future.
Cellino, twice convicted of fraud and awaiting trial for allegations of embezzlement - a charge he denies - needs to pass the League's 'owners and directors test' before any transaction can be authorised, essentially a judgement of whether he is a 'fit and proper' person to own and run a football club.
But Friday's statement from the League suggests he has yet to reach that stage.
