LOS ANGELES (AP) — Pac-12 schools have agreed to perform COVID-19 and coronavirus antibody tests on all athletes upon their return to campuses for voluntary workouts.

“These guidelines are coming from our medical advisory committee and it’s their belief this is best practice,” Commissioner Larry Scott told The Associated Press.

Scott said athletes will continue to be tested regularly for COVID-19 as long as they are under the supervision of the schools.

“I think it’s important to keep in mind our student-athletes come from all over. All over the United States and in some cases all over the world,” Scott said. “Return to campus and return to voluntary workouts I think factors that in.”

The Pac-12 schools are scheduled to begin allowing athletes back into their facilities for voluntary workouts starting June 15.
