Bradford City are appealing for fans to return some of the tickets for the home fixture against Liverpool because the seating arrangements have been changed.
Some supporters who bought tickets for the original match, postponed on December 30, are being urged to swap them for other tickets as soon as possible before the rearranged game next Tuesday, May 1.
The plea affects fans with tickets for the CIBA Stand Block E (seats 134-140), Block F and Block G. Liverpool fans will now use that area of the ground instead of the North West Corner Stand, which they were originally allocated.
A Bradford spokesman said: "We would like to apologise for the inconvenience that this will cause those supporters affected and would also like to remind season ticket holders that they should redeem voucher 30 at the turnstiles.
"Season ticket holders will occupy the seats they have had since the Manchester City game."
