The San Francisco 49ers will play their next two home games in Arizona after revised coronavirus restrictions prohibited them from doing so at Levi's Stadium.

On Saturday the Santa Clara County Public Health Department announced new directives to curb the spread of COVID-19 amid a surge in cases in the area. 

The new measures ban recreational activities at all levels that "involve physical contact or close proximity to persons outside one’s household, including all contact sports".

With the restrictions set to last for at least three weeks, the 49ers were left needing to find an alternative venue for practice – which is usually held at a facility adjacent to Levi's Stadium – and for their upcoming home games with the Buffalo Bills on December 7 and the Washington Football Team on December 13.

And the Arizona Cardinals have stepped in to assist their NFC West rivals, permitting the 49ers to use State Farm Stadium for those matchups.

A statement from the 49ers read: "The San Francisco 49ers have come to an agreement with the National Football League and Arizona Cardinals which allows the 49ers to host their Weeks 13 and 14 home games against the Buffalo Bills and Washington Football Team at State Farm Stadium in Arizona.

"The Cardinals organisation, State Farm Stadium and League officials have been supportive and accommodating as we work through the many logistical issues involved in relocating NFL games.

"Information regarding the 49ers future practice arrangements will be shared at the appropriate time."

49ers CEO Jed York posted on Twitter: "Thank you [Cardinals owner] Michael Bidwill and the @AZCardinals for all of your help. Very appreciative of Arizona welcoming us during these unprecedented times."

The Niners beat the Los Angeles Rams 23-20 on Sunday to move to 5-6, one game behind the Cardinals in the race for the final spot in the NFC playoffs.
