The coronavirus pandemic continues to have a profound impact on American life and culture, including in the world of sports. Just hours after a trio of persons affiliated with the Philadelphia 76ers tested positive for coronavirus, the Los Angeles Lakers revealed two players have tested positive. Now, the Boston Celtics have announced one of their players tested positive, as well. The organization issued this statement on Thursday:

The Boston Celtics learned today that a player has tested positive for COVID-19. Testing was initiated because of exposure to a known positive case.

The full statement can be found in the tweet below:

From the looks of things, the player was Marcus Smart, who is asymptomatic but also urging fans to take the threat seriously.

Clearly, the illness is having an especially profound impact in the NBA. There have been cases discovered among two minor league baseball players, and New Orleans Saints head coach Sean Payton announced earlier on Thursday he had tested positive.

However, in terms of known cases, the NBA dwarfs other sports.

The league has taken swift action in the last week and–shortly before it was announced that these players all tested positive–shut down all practice facilities indefinitely on Thursday. Officials also encouraged players and coaches to remain in their respective markets, though they will allow players to return home.

As far as the Celtics go, their market may be disproportionately impacted. Marc Fortier of NBC 10 Boston reported the state of Massachusetts saw the largest one-day increase of confirmed cases on Thursday:

There are now 328 total coronavirus cases in Massachusetts, up 72 from a day earlier.

It's the largest spike since the number of cases jumped from 41 to 92 back on March 10, the same day Gov. Charlie Baker declared a state of emergency.

Massachusetts is one of the states in the U.S. with the most coronavirus cases in the country so far. While no one has died from the virus locally, more than 150 people have died nationwide, two of them in Connecticut.

This pandemic is not going away anytime soon.
