KANSAS CITY, Mo. -- Kansas City Chiefs safety Tyrann Mathieu has been placed on the league's reserve/COVID-19 list after testing positive for the coronavirus, sources told ESPN.
Mathieu is vaccinated, according to a source.
To be moved off the COVID-19 list and cleared to play, Mathieu will need to test negative twice within a 24-hour period.
The Chiefs have only three other safeties on their 53-player roster following Tuesday's cuts. But Mathieu has time to be available before the Chiefs open the regular season on Sept. 12 against the Cleveland Browns at Arrowhead Stadium.
