PRESS ASSOCIATION -- The chance to buy more than 1.5 million unsold Olympic tickets opens on Friday at 6am.
There are 1.5 million football, 40,000 volleyball and 8,000 freestyle wrestling tickets available on a first-come first-served basis.
They are being offered to the 700,000 applicants who got all or part of their ticket requests in the first-round sale which closed in
This sale runs from July 8 at 6am to July 17 at 6pm. The tickets cover 58 sessions and 130 price categories.
London 2012, who have sold over 3.5 million tickets so far from around 850,000 applications, said all other sports have no availability.
Chairman Lord Coe told the International Olympic Committee (IOC) there had been inevitable disappointment from the "phenomenal and unprecedented" demand for Olympic seats.
Reporting on progress of next year's Games to the IOC session in Durban, South Africa, he said: "Both domestically and internationally the demand for tickets has been phenomenal. I would actually say it has been unprecedented - 1.9 million people applied for 22 million tickets. We have 6.6 million to distribute.
"We have sold out in 23 out of 26 sports, that's an extraordinary vote of confidence in Olympic sport, not just in Britain but around the globe. We promised full venues and affordable prices. There has been disappointment, with that level of demand it is inevitable."
Of the tickets available, 1.5 million are for football, including the men's and women's matches at Wembley Stadium, City of Coventry Stadium, Millennium Stadium, Hampden Park, St James' Park and Old Trafford.
Football made up the bulk of the tickets available in the second-chance sale as the matches are played in large venues. There are around 40,000 volleyball tickets, where men's and women's sessions are based at Earls Court. Around 8,000 freestyle wrestling tickets, staged at Excel, are also for sale.
