The Latest on the Tokyo Olympics, which are taking place under heavy restrictions after a year’s delay because of the coronavirus pandemic:

A map on the Olympic website has been changed after Ukraine protested that it included a border across the Crimean Peninsula.

The map is part of a “Cheer Zone” feature tracking how fans around the world have backed different teams at the Tokyo Games.

Late Thursday the map had a black line across the top of Crimea in the same style as national borders. On Friday morning, there was no line across the peninsula. Russia annexed Crimea from Ukraine in 2014. Ukraine still considers it to be Ukrainian territory.

The Ukrainian embassy in Japan tells the Associated Press in an e-mail that “we have protested to the IOC and the map was corrected.”

Road cyclist Michal Schlegel is the fourth Czech athlete from three different sports to test positive before their competition at the Tokyo Games.

Schlegel tested positive at the team’s training base in Izu and will miss Saturday’s road race.

The Czech Olympic Committee said in a statement Friday that Schlegel is in isolation, and that Michael Kukrle and Zdenek Stybar will be its only two riders lining up at Musashinonomori Park for one of the first medal events of the Summer Games.

Czech beach volleyball players Marketa Slukova and Ondrej Perusic and table tennis player Pavel Sirucek also tested positive earlier this week. That has prompted the Czech Olympic team to investigate whether the outbreak is linked to its chartered flight to Tokyo.
