Boston Celtics forward Jaylen Brown will miss Saturday's preseason matchup against the Toronto Raptors after entering the league's health and safety protocols, the team announced. 

The Celtics say Brown has tested positive for COVID-19 although he is without symptoms. Brown is currently isolating in accordance with the NBA's protocols.

The 24-year-old is entering his sixth season with the Celtics after being selected No. 3 overall in the 2016 NBA Draft.

Boston will play three more preseason games before opening the regular season in Madison Square Garden against the New York Knicks on Oct. 20.
