"Everybody saw how we played against Canada with masks and took them off after the second period, when we received the results of our tests. They were all negative,” Bobariko told the state news agency, per Reuters.
But Bolgareva’s results “turned positive” upon returning to the Olympic Village after the game, the coach said.
“I don’t understand how this is happening,” he added.
Bolgareva played 17:39 against the U.S. on Saturday, a 5-0 U.S. win.
