Michigan coach Jim Harbaugh says he would have no issue playing college football this fall in empty stadiums.

Harbaugh, appearing Wednesday morning on ESPN’s “Get Up!” with host Mike Greenberg, was asked if he would be comfortable with that option. College athletics were suspended in March because of the COVID-19 pandemic, and it is unclear across the country whether students will return to campus this fall and whether or how fall sports can be played.

During the interview, Harbaugh discussed the potential for COVID-19 testing for players and coaches from both teams and for officials before every game. But having testing available for fans attending Michigan Stadium, the largest stadium in the country with a capacity of 107,601, would likely be problematic.
