The NCAA’s Big Ten Conference announced the postponement of all fall semester sports including college football on Tuesday, citing concerns related to the coronavirus pandemic.

“The mental and physical health and welfare of our student-athletes has been at the center of every decision we have made regarding the ability to proceed forward,” said Big Ten Commissioner Kevin Warren.

“As time progressed and after hours of discussion with our Big Ten Task Force for Emerging Infectious Diseases and the Big Ten Sports Medicine Committee, it became abundantly clear that there was too much uncertainty regarding potential medical risks to allow our student-athletes to compete this fall.”
