Two NFL teams have decided to temporarily shut down operations following an uptick in positive COVID-19 tests. ESPN’s Chris Mortensen and Adam Schefter reported the news on Tuesday morning.

The Tennessee Titans and Minnesota Vikings are pausing all team activities right now, after three Tennessee players tested positive, as well as five personnel members. The two teams played each other over the weekend.

“Out of an abundance of caution, the organization has decided to work remotely today as we follow NFL protocols related to the Covid-19 virus,” the Titans said in a statement. “Several tests have come back positive and we are working through the process of confirming them. We will have more information tomorrow.”

Players, staff and personnel who test positive for the virus are required to quarantine, according to the NFL’s rules and guidelines related to the pandemic. Those in contact with individuals who test positive will need to produce a negative test before they’re permitted to return to team activities.

“Both clubs are working closely with the NFL and NFLPA, including our infectious disease experts, to evaluate close contacts, perform additional testing and monitor developments,” the NFL said in a statement. “All decisions will be made with health and safety as our primary consideration. We will continue to share updates as more information becomes available.”

The Titans defeated the Vikings 31-30 on Sunday. Tennessee is 3-0 this season and Minnesota is 0-3.
