Hull have been promoted to the top flight for just the second time in their 109-year history on a dramatic afternoon at the KC Stadium in which they were forced to wait 20 minutes before their fate was determined.
Steve Bruce's men were unable to secure the three points against the champions which would have guaranteed them second spot, yet they had a helping hand from Yorkshire rivals Leeds who beat third-placed Watford 2-1.
With just minutes to go in the Tigers' game, they were heading up against the 10-man Bluebirds yet an incredible finale with one red card, two penalties and a mini pitch-invasion left the door open for Gianfranco Zola's 10 men at Vicarage Road.
However, with their clash delayed due to an injury, they were unable to score the goal which would have sent them into the top flight and it was Ross McCormack who scored instead to give Leeds a 2-1 win and send the Tigers into delirium.
Former Hull loanee Fraizer Campbell had threatened to derail the Tigers' hopes by breaking the deadlock just after half-time, but two goals in five minutes through Nick Proschwitz and Paul McShane looked to have turned Hull's entire season back around.
Andrew Taylor was then sent off before Proschwitz had a penalty, which would surely have guaranteed promotion, saved.
Instead, Nicky Maynard earned Cardiff a share of the spoils from the penalty spot although matters at Vicarage Road would ultimately transpire in Hull's favour.
