GALT (CBS13) — Friday marks the first day that high school football games, which have been on hold since last year due to the pandemic, can resume in California – but positive COVID-19 tests are derailing those plans.

On Thursday, Galt High’s varsity football team was put on quarantine by the county health department due to three positive cases. Three or more positive cases is considered an outbreak, officials say.
