The team will not be allowed to play games or practice at its usual home for at least three weeks as a result of COVID-19 restrictions in effect in Santa Clara County, California. Per Steve Gardner of USA Today, there is a temporary ban on all high school, collegiate and professional contact sports.
There is also a mandatory quarantine for anyone traveling to the county, potentially creating a longer time away.
Arizona is home next Sunday, however, which could create a quick turnaround to prepare the stadium before San Francisco's game Monday.
San Diego's SDCCU Stadium used to host the Chargers but has been inactive after the team moved to Los Angeles. The venue is set to be demolished in 2021 but could have value over the next few weeks if used by the 49ers.
