The Oct. 10 Angelus League game between Cathedral and host Salesian is expected to be switched to Saturday afternoon, Oct. 11, at a neutral site, Salesian Principal Sam Robles said.
The two rival schools haven't played in years.
Salesian's stadium seats about 1,700.
Last week, during Salesian's scrimmage against Compton Dominguez, the scrimmage was ended after a pushing incident involving players and then an incident in the stands in which a Salesian parent was punched.
The school is investigating the incident in the stands.
