The MAC has postponed all fall sports until at least the spring, becoming the first FBS conference to make the decision.
League presidents met Saturday morning and voted unanimously for the postponement.
MAC commissioner Jon Steinbrecher said the decision "was not made lightly nor without significant contemplation and conversation over the past weeks."
"Clearly we are charting a conservative path -- and it is one that has been recommended by our medical advisory group," Steinbrecher told reporters on a video conference. "There are simply too many unknowns for us to put our student-athletes in situations that are not clearly understood. We have traditionally been a leader on student-athlete well-being issues. This has not been an easy decision. For the Mid-American Conference, it is the right decision."
