(AP) — The Atlanta Falcons say they have shut their facility following one new positive test for COVID-19.

Defensive tackle Marlon Davidson was placed on the COVID-19/reserve list this week. The addition of a second unidentified person caused the Falcons to act out of caution.

A team spokesman said the second person was not a player. The spokesman added that, barring any changes, the Falcons are expected to be back at their facility on Friday.
