KANSAS CITY, Mo. — The Big 12 Tournament in Kansas City has been canceled as concerns continue to mount over the spread of COVID-19 in the country.

Commissioner Bog Bowlsby said Thursday that he never heard from any players who didn't want to play because of the risks, but said the virus is at the top of student-athletes' minds.

Bowlsby met with athletic directors from each of the Big 12 schools ahead of the cancellation. He said there was a collective feeling of sadness over the decision.
