Members of the team were confined to their rooms and undergoing Covid testing on Thursday afternoon, less than 24 hours out from the start of track and field events on Friday in Tokyo.
“Members of Australia’s track and field team at the Tokyo Olympic Games are isolating in their rooms as a precautionary measure following news of a Covid positive finding with a member of the US track and field team,” an AOC statement read.
“Members of the Australian track and field team are now undergoing testing procedures in line with Australian Olympic team protocols.”
Australian vaulter Kurtis Marschall had been training with Kendricks before the American’s withdrawal and the Commonwealth Games gold medal winner now faces an anxious wait to learn his test results.
The men’s pole vault heats begin on Saturday at the Olympic Stadium.
Two-times world champion Kendricks earlier withdrew from the Games after returning a positive Covid test, the United States Olympic and Paralympic Committee confirmed.
“The health and safety of our athletes, coaches and staff is our top priority,” the USOPC said in a statement.
