BRUSSELS (AP) -- Both London and Doha say they would not consider hosting the 2019 world championships as a part of a possible IAAF deal to satisfy both bidders for the 2017 event.
The executive director of the Qatari bid, Abdualla Al Zaini, says he is "not considering any other date" than 2017.
London bid chairman Ed Warner says the financial commitments can not be switched and "we are in no position" to accept the 2019 event.
The British and Qatari capitals are vying for the 2017 championships. The decision is set to be made Friday in a vote of the International Association of Athletics Federations in Monaco.
Because both cities are strong candidates, the IAAF has been considering a deal to also award the 2019 championships.
