In a team press release, the Celtics announced All-Star Jaylen Brown tested positive for COVID-19 on Friday. They added that Brown is asymptomatic and quarantining.

It’s unclear at this time whether his quarantine duration will extend to the start of the regular season (October 20, at the Knicks), but he will almost certainly miss the team’s last three preseason games.

It’s a tough blow for Brown, 24, who is also returning from wrist surgery. Brown had a stellar season in 2020-21, averaging 24.7 points, 6.0 rebounds and 3.4 assists per night in 58 games. He also had a career-best shooting line of .484/.397/.764.

If Brown does end up missing regular-season games, offseason acquisitions Dennis Schröder and Josh Richardson are likely to fill in for the bulk of his minutes.
