Town are heading towards a sell-out against Leeds at the weekend with 27,000 tickets already sold for the Championship clash.
The Elland Road club have sold their ticket allocation with 2300 fans from the Yorkshire club heading to Portman Road for the 'game of the day' in the division.
"It's the biggest selling game of the season here so far," Town's Ticket and Call Centre Manager John Ford confirmed to the Club website.
"We have sold over 27,000 tickets and the phones have been busy all week.
"We will be closing in on a sell-out if the rate of interest continues but we still have clear view seats in the North Lower, Greene King upper and lower available at the moment.
Jermaine Wright - back at Town
The match will see the return to Portman Road of another former Town player, with Jermaine Wright looking set for a place in the Leeds midfield on Saturday.
The 29-year-old moved to Elland Road in the summer after coming to the end of his contract with Blues.
