Minnesota and Wisconsin canceled their football game scheduled for Saturday in Madison.
On Wednesday, the Gophers men's basketball team is scheduled to play its first game of a season that, if the season is played to its scheduled conclusion, will result in an NCAA tournament contained inside a large bubble in Indianapolis.
Since the virus became a widespread concern earlier this year, we have seen all manner of sporting approaches to playing during a pandemic.
The WNBA and NBA played in bubbles in Florida — bubbles so well-maintained that even Florida Man couldn't stumble in to ruin their seasons.
The NHL played in bubbles in Canada, running screaming from proposals to play in cities such as Las Vegas or Los Angeles because America has failed every common-sense test regarding COVID-19.
Basketball and hockey provided ideal models. Baseball played a regular season relying on the common sense of its players and employees and, after many notable outbreaks, completed the regular season and then completed its postseason in bubbles, with few incidents until the Dodgers' Justin Turner decided to return to the field after testing positive during the final game of the World Series.
It's a team game. If one player gets the virus, why shouldn't they all share it?
The NFL has postponed games and remains vulnerable to breakouts. Most likely, Thursday's game between the Steelers and Ravens will have to be postponed after the Ravens reported a handful of new positive tests.
