Report: 49ers could share Cardinals' stadium amid new restrictions

The San Francisco 49ers and Arizona Cardinals could share State Farm Stadium in Glendale due to new COVID-19 restrictions in California's Santa Clara County, sources told NFL Network's Ian Rapoport.

Amended protocols in Santa Clara County - where the 49ers reside - ban all contact sports and require individuals to quarantine for 14 days if traveling into the region from 150 miles away. The rules take effect Monday and apply to professional, college, and recreational sports teams.

The 49ers said Saturday they are working with the NFL on operational plans.

Arizona has long been viewed as a potential partner for the 49ers if COVID-19 protocols in the Bay Area tightened. The NFL calibrated the 2020 schedule such that the 49ers and Cardinals never play home games on the same day, allowing them to share a venue if necessary.

San Francisco has three home games remaining. If the 49ers do move into State Farm Stadium, they'll need to figure out where to practice and house the team. They could reportedly move to Texas if the Arizona contingency falls through.
