Southampton have been effectively relegated after being docked 10 points by the Football League.
The ruling comes after Saints' parent company went into administration, though the club and administrators say they expect to launch an appeal.
Four points off safety with two games to go, Saints will lose 10 points if they stay up in the Championship.
And if they do not avoid finishing in the bottom three then the points penalty will take effect next season.
The south coast outfit had hoped to avoid the punishment as they argued that it was their parent company Southampton Leisure Holdings plc (SLH) which had gone into administration on 2 April - not the football club.
But a League investigation by "independent forensic accountants" found that the football club and SLH were "inextricably linked as one economic entity" and applied their mandatory penalty.
The League also found that: "The holding company has no income of its own; all revenue and expenditure is derived from the operation of Southampton Football Club and the associated stadium company.
"The holding company is solvent in its own right. It only becomes insolvent when account is taken of the position of Southampton football club and the other group companies."
The statement added that there was no alternative other than to invoke the 10-point penalty.
It was also revealed that the company commissioned to look into the matter reported that co-operation with them was withdrawn towards the end of their enquiries.
However, Mark Fry, joint administrator of SLH, insisted he was "shocked and extremely disappointed" with the League's decision to deduct points.
