The Pac-12 will work with both schools to try to reschedule.
The game was originally scheduled for Dec. 13, but was called off because of a case of COVID-19 within the USC program.
Stanford has also had games canceled or postponed against Utah Valley, Cal Poly, Loyola Marymount, Sacramento State and Oregon State. USC's list includes San Francisco, Oregon State and Texas Southern.
