SEATTLE -- Fans attending most pro sporting events in Seattle will soon be required to show proof they've been vaccinated against COVID-19 or that they've tested negative for the virus.
The NFL's Seahawks, MLS's Sounders, NHL's Kraken and MLB's Mariners, along with the University of Washington and Washington State University, all announced updated policies Tuesday for fans attending games this season.
The Seahawks will be the first to implement the requirements, starting with their Sept. 19 home opener against Tennessee. Fans will be required to show proof of vaccination or a negative test taken within 72 hours of the event to be granted entry.
Team president Chuck Arnold said in a statement that the measures will allow for a full stadium while keeping the experience safe.
Washington will begin an identical verification process for fans with its Sept. 25 home game against California. The Sounders will begin with their Oct. 3 match against Colorado. Washington State said its verification process will begin in October.
The Mariners said fans should plan to provide proof of vaccination for any potential postseason games the team hosts. The team also said all front office, event staff and Mariners employees at team operated facilities in the U.S. were told in late August they must be fully vaccinated by Oct. 4 as a condition of employment.
While the other Seattle teams are permitting a negative test to gain entry, the Kraken will only allow vaccinated fans at games.
