Ewing, who won an NCAA championship in 1984 as a Georgetown player, said he wanted to thank healthcare workers and everyone on the front lines of the pandemic.
“I’m fine and we’re all going to get through this,” said Ewing.
The university said Ewing was isolated in a hospital. He is the only person in the program to test positive for the virus, said Georgetown.
Ewing has spent most of his career in the NBA with the New York Knicks, but has also had stays with the Seattle SuperSonics and the Orlando Magic. He scored almost 25,000 points and recorded more than 11,000 rebounds in 17 years of career.
He was inducted into the Naismith Memorial Basketball Hall of Fame in 2008.
He has been a coach at Georgetown since 2017.
