Three days after announcing he had tested positive for Covid-19, Sacramento Kings forward Jabari Parker was spotted playing tennis in Chicago without a mask, after reportedly going out to a restaurant recently.

TMZ published a pair of photos showing Parker playing tennis without a mask, and said the photos were taken earlier that day.

The outlet also reported that "Jabari was recently seen out at a restaurant there in the Windy City."

While it is unknown exactly when Parker tested positive or the current status of his recovery, the club released a statement to the Sacramento Bee on Saturday after the TMZ report surfaced.

"We are aware of the report and are gathering additional information," the statement read. "We have no further comment at this time."

The NBA requires any player who tests positive for Covid-19 to refrain from physical activity for a minimum of 14 days.

Parker, 25, said in a statement Wednesday that he had tested positive for COVID-19 "several days ago" and that he was isolating in Chicago.

He added he planned to join his teammates next month at the ESPN Wide World of Sports Complex at Disney World, Orlando, when the NBA season resumes.

Parker's team-mate Alex Len also announced Wednesday that he, too, had tested positive for the virus. Fellow Kings player Buddy Hield also reportedly tested positive for Covid-19, though neither the Kings nor Hield have made any announcement.

The NBA revealed on Friday that 16 of 302 players had tested positive, a little over a month before the 2020 season is set to resume.

By contrast, the English Premier League has had just 17 positive results from 10,230 tests on players and staff and no-one tested positive from almost 900 tests at League of Ireland sides Dundalk, Shamrock Rovers, Bohemians and Derry City.

NBA teams will begin arriving in Florida for training camp by 11 July, and the season will resume 30 July, having gone on hiatus on 11 March.
