Professional sports are back, but are they safe?

Leagues say yes. And the vast majority of athletes have chosen to compete. But doctors surveyed by SI tell a more complex story: They worry COVID-19 could cause many serious health problems down the road, and say that sports played outside a bubble are not worth the risk—even for young, healthy athletes who get paid millions to play.

Sports Illustrated asked doctors with expertise related to COVID-19 around the country: If your full income came from playing in one of the four major U.S. men’s professional sports leagues, how likely would you be to play?

The results were stark. Roughly 90% of the 146 doctors who responded to SI’s survey said they would definitely or probably play in the NBA (which has built a locked-down “bubble” in Orlando) or the NHL (which has two bubbles in Canada). But majorities said they probably or definitely would not play in the NFL (62%) or Major League Baseball (59%) under current protocols.

Regarding the NHL, 43.8% of the surveyed responded would definitely play, 47.9% said probably play.
