Football and men’s water polo workouts will not resume until at least Sept. 8, the University announced Monday.

Workouts paused last Wednesday when eight players from the football and water polo teams tested positive for COVID-19. Another athlete from one of those two teams tested positive Friday. All players who tested positive have since been moved to isolation.

The University says the possibility of it having been transmitted by any coaches, staff or other athletes is “very low.” Rather, the virus was likely contracted off campus.

These nine student-athletes contracted COVID-19 nearly concurrently with 104 other USC students who have tested positive for the virus since returning to campus and the surrounding area.

The University will test all athletes twice a week for the foreseeable future. Football and men’s water polo will not resume workouts until results are released from the next two rounds of testing today and Friday.

When they resume, all workouts will continue to be non-contact and take place outdoors, in compliance with current Pac-12 conference and public health guidelines. Athletes who work out on campus will continue to be required to complete symptom questionnaires, undergo temperature checks, wear masks or face coverings, practice social distancing and use hand sanitizer regularly.

Among all USC sports that have begun practicing on campus — football, men’s water polo, women’s soccer, women’s volleyball and men’s and women’s basketball — 16 athletes have tested positive for COVID-19 since mid-June. Football and men’s water polo remain the only teams whose practices have been affected.
