Rick Carlisle has been cleared to travel to Washington for Saturday's game after missing the Dallas Mavericks' 99-86 win over the New York Knicks on Friday.
Carlisle, who was vaccinated in January, tested positive for COVID-19.
"There's a chance and a hope that it will be a false positive. This seems like possibly a mistake, but for these reasons I'm entering the [NBA health and safety] protocol," said Carlisle.
Assistant Jamahl Mosley coached the Mavs on Friday night.
