Leeds United say they will honour a promise to partially refund fans who bought season tickets for 2016-17 if they miss out on the play-offs.
Barring a 14-goal swing in the final round of fixtures, Garry Monk's side will now finish outside the top six.
Fans who bought a season ticket for the Championship club before the end of May 2016 will get 25% of their money back.
The club had pledged to give refunds of 50% if they sold 15,000 tickets, but they did not reach that number.
Leeds, who have extended a deadline for supporters to claim their money back, are in the process of sending forms to season ticket holders who qualify for the refund.
The cost to the club, co-owned by Italian businessman Massimo Cellino, is not known, but it is understood that funds have been ring-fenced to pay back the money.
Speaking after Saturday's 3-3 draw with Norwich, which effectively ended their play-off hopes, manager Monk said: "The reality is, the majority of the group were not quite ready for this situation. That's not a criticism. It's just a fact."
