NASHVILLE, Tenn. — The Tennessee Titans won’t be back inside their building until Saturday at the earliest because of eight positive tests for the coronavirus, the first outbreak to hit the NFL as it tries to play a full schedule amid the pandemic.

Tennessee is scheduled to host Pittsburgh in a matchup of two of the league’s seven remaining undefeated teams on Sunday, and Steelers coach Mike Tomlin said his team has been “given a mandate” to prepare as if the game will be played on time — even if the Titans are unable to practice.

“We’re going to trust the medical experts,” Tomlin said. “If they deem it safe for us to proceed, we’re going to go down there playing to win.”

Tennessee suspended in-person activities through Friday after the NFL said three Titans players and five personnel tested positive for the coronavirus. The NFL had played three weeks without a COVID-19 outbreak. Now, the Titans will become the first significant in-season test of the league’s virus protocols.

The Titans placed a pair of key players, defensive captain and lineman DaQuan Jones and long snapper Beau Brinkley, on the reserve/COVID-19 list Tuesday.
