Spurs asked to move the third-round clash to Milton Keynes, 50 miles outside London, because their new £850million stadium is still not ready and Wembley is unavailable following Anthony Joshua’s world heavyweight title fight against Alexander Povetkin on Saturday.
Dons season-ticket holders can buy up to four seats from Tottenham’s allocation for a section of the upper tier at the 27,500-capacity home of the League Two club.
Tottenham could have asked for the fixture to be staged at Watford but did not pursue that option.
Around 14,000 of Spurs’ 50,000 season-ticket holders have already bought tickets, and seats will remain on sale to fans listed on all three clubs’ databases until 5pm today. Watford have an away allocation of 4,500. No tickets will be available on the gate.
Paulo Gazzaniga is expected to continue in goal for Spurs after being named man-of-the-match in Saturday’s 2-1 win at Brighton, with Hugo Lloris (thigh) and Michel Vorm (knee) still sidelined. Lloris may return against Barcelona on October 3.
