Once the COVID-19 pandemic is under control, there will be substantial hurdles for sports leagues. One challenge will be the leagues’ capacity to test players, coaches and referees in as close to real-time as possible. Current tests for coronavirus take at least a day and up to several days to get results.

This is a big concern for team-based sports like the NBA, NHL, MLB and NFL. SI’s legal analyst Michael McCann breaks down how the potential for real-time COVID-19 testing may result in the return of sports sooner rather than later.
