The 2016 Paralympics in Rio de Janeiro will be a sellout, the Games' organizing committee has predicted less than three weeks after it was revealed that just 12 percent of tickets had been sold.
Concerns were raised that events would be played out at empty venues after the local organizing committee shared the disappointing sales figures towards the end of the Olympics.
However, the International Paralympics Committee now says that 1.5 million tickets have been sold, and the governing body is optimistic about the remaining million.
An IPC statement read: "Several finals are now fully sold out. The Paralympic athletes can be prepared to display their amazing will and skills in fully booked venues.

"While there are still around one million tickets available, the rhythm of sales suggests that all the 2.5 million tickets will be sold."
Rio 2016 communications chief Mario Andrada added: "There has been an important change of the pattern as far as ticket sales are concerned. Firstly we saw a lot of energy coming from the Olympic Games and from people who just wanted to have access to the Paralympic Park at Barra. Now we see people look for specific athletes and scheduled duels.
"To see sport as the main reason for people to buy a given set of tickets is very rewarding."
The Paralympics have been plagued by budget cuts in the buildup to Wednesday's opening ceremony, with workforce, transport and venue funding slashed.
