It looks like fans will be returning to the stadium and soon.
The statement posted verbatim as possible:
We’re excited to safely welcome fans back to Earthquakes Stadium when the 2021 Major League Soccer season kicks off next month. The Quakes appreciate Santa Clara County and the California Department of Public Health for their respective guidance to keep our community safe, and we’re looking forward to continue making our home a welcoming meeting place for all.
In the most restrictive purple tier, capacity will be limited to 100 people and attendance will be limited to regional visitors. Capacity will be limited to 20% in the red tier, 33% in the orange tier, and 67% in the least-restrictive yellow tier. Attendance at outdoor sporting events will be limited to in-state visitors, regardless of tier.
The schedule is yet to be announced but April 16 is when the league begins play.
