NASHVILLE, Tenn. — The Tennessee Titans were told players could not gather together for any in-person activities either at the club’s facility or elsewhere a day before several Titans worked out at a private school, a person familiar with the situation told The Associated Press on Thursday.

The NFL closed both the Tennessee and Minnesota facilities Sept. 29 after eight positive test results for the Titans. A group of Titans, including quarterback Ryan Tannehill, worked out at Montgomery Bell Academy in Nashville on Sept. 30 after getting permission from coaches at the school.

There wasn’t language in the CBA or COVID protocols related to working out after being told not to, or in case of an outbreak at a team’s facility.

The Titans’ outbreak increased to 23 Thursday with tight end MyCole Pruitt and a defensive back from the practice squad placed on the reserve/COVID-19 list Thursday afternoon. The Titans’ facility remains closed with the team still prohibited from any in-person activities.

Tennessee (3-0) has had 21 positive tests returned since Sept. 29, putting Sunday’s game with Buffalo (4-0) at risk of at least being postponed. Buffalo is scheduled to host Kansas City on Oct. 15.

A scenario the NFL has been considering is moving the Bills-Titans game to Monday or Tuesday night, moving Chiefs-Bills to next weekend, and not having a Thursday night game. The NFL postponed the Titans’ game last weekend against Pittsburgh and eventually moved it to Oct. 25.

Buffalo safety Micah Hyde said the Bills want to play. He thought the league should have made a decision by Thursday.

“We’re not really sure what’s going on,” Hyde said. “Honestly, we’re clueless (with) the situation coming up. So all we can do is practice and prepare like we’re going to play on Sunday, and I think everybody in this building wants to play.”

Bills center Mitch Morse said the team has been getting updates through the media on an “ever-evolving situation.”

“It’s really up in the air,” Morse said. “I think it’s an ongoing, evolving situation that all parties involved are trying to do the right thing. I think player safety is No. 1, and then trying to get this game going is the utmost importance for a lot of people, but not at the cost of players’ health.”

The investigation by the NFL and the players’ association into how Tennessee turned into the league’s first COVID-19 outbreak found “several specific incidents” of the Titans possibly breaking protocols dealing with the coronavirus pandemic, a person with knowledge of the inquiry told the AP on Wednesday.

NFL Commissioner Roger Goodell warned all 32 teams Monday that following league protocols is mandatory and that violations forcing changes in the schedule could lead to being stripped of draft choices or even forfeiting games. The NFL also updated protocols on Oct. 2.

Dr. Allen Sills, the NFL’s chief medical officer, said Wednesday that the investigation included video inside the Titans’ facility, interviewing everyone involved and studying seating charts on buses and planes.

Sills noted they wanted to learn how to improve, and the NFL already has made a number of changes.

The NFL sent new protocols to all 32 teams Oct. 1 detailing additional steps including a second daily test when dealing with an outbreak or having been exposed to an outbreak.

Miami Coach Brian Flores said all coaches and players can control is how they practice and follow protocols, not whether games are played or postponed.

“Do you start to think about, ‘OK, if we start canceling more games or postponing more games, what’s that going to look like for the rest of the season?’ Yeah, but I try not to look that far down the road,” Flores said. “I think the league will handle those things, and if we end up being affected, then so be it.”

NOTES: The Titans also announced that tight end Tommy Hudson, a practice squad member currently on the reserve/COVID-19 list, has been suspended without pay for six games for violating the NFL’s policy on performance-enhancing substances.
