Supporters have until noon to purchase the remaining 190 seats for this evening's Carling Cup tie at Northampton.
The Sixfields tie is all-ticket and no tickets will be sold after Midday, either at Loftus Road or at this evening's venue.
Supporters are therefore advised not to travel if they do not have a valid ticket for this evening's fixture.
Should tonight's First Round game end all square after 90 minutes, extra time will be played.
If there is still no winner the tie will be decided by penalty kicks.
