World Athletics President Sebastian Coe is confident that all female athletes at this year's world championships in Tokyo will have undergone gene testing, after snags left some of them scrambling to meet the Sept. 1 deadline.
Athletes who arrive at the Sept. 13-21 global event without being tested can complete the process in the Japanese capital.
"Although the vast majority of athletes will have been tested before they get to Tokyo ... if there are outstanding athletes that still haven't been tested, we have the ability to do that in Tokyo — but that is by no means an invitation for member federations to wait until they get to Tokyo," Coe said on a video call on Thursday.
