The NCAA released its updated COVID-19 guidance for winter sports on Thursday, adjusting its definition of "fully vaccinated" individuals and also updating its suggested protocols following a positive test.

"The omicron variant has presented another surge of cases across the country," NCAA chief medical officer Brian Hainline said. "This guidance was designed to align with the latest public health directives. Given how the pandemic continues to evolve, it's important that staff on member campuses continue to work with their local and state health officials on protocols most suitable for their locations."

The NCAA COVID-19 Medical Advisory Group developed its new definition of "fully vaccinated" to account for vaccinations, boosters and other immunity factors.
