Representatives of the NFL Players Association were told by team physicians Thursday night that those doctors believe teams’ training camps can be opened safely in areas of the country experiencing explosive growth in cases of the novel coronavirus.

NFLPA leaders revealed the conversations Friday during a video conference call with reporters. The discussions with the team doctors were arranged to attempt to assuage the NFLPA’s concerns about opening camps in “hot spot” cities.

“The doctors last night on the call said, with a couple of reservations, that they felt it was safe to open training camp,” said DeMaurice Smith, the union’s executive director. “They provided their medical reasons. Some of the things we agreed with. Some of the things we may not agree to. But overall, they gave their medical opinion that it was safe to open training camp, and that’s where we are.”

NFLPA leaders said it is the league’s prerogative to decide when training camps will open. The union’s focus, they said, is on ensuring players will be healthy and holding the league accountable for having effective medical protocols.

“We ask the questions of whether it’s safe,” said Cleveland Browns center JC Tretter, the NFLPA’s president. “That’s why we had the call last night with the physicians from these locations, asking them about these same issues, about whether it’s safe to bring players back and families back to these locations, whether it’s smart. … It’s up to the NFL to make those decisions on when we open.”

Team owners and league leaders spoke by video conference Friday. The league issued a statement afterward saying it remains committed to playing a full 2020 season.

“We will continue to implement the health and safety protocols developed jointly with the NFLPA, and based on the advice of lea​ding medical experts, including review by the [Centers for Disease Control and Prevention],” the statement said. “We will address additional issues in a cooperative way. All decisions will be made in an effort to put us in position to play a full regular season and postseason culminating with the Super Bowl which is the shared goal of the clubs and the players.”

The league sent coronavirus-related educational material to players and teams Friday. As the NFL and NFLPA continue to discuss unresolved issues such as testing frequency and opt-out rules, one person familiar with the discussions said there was reason for optimism.

“I think we’re moving in the right direction,” that person said. “There’s a chance camps could start on time.”

Most NFL teams are scheduled to open training camp July 28, but some have their rookies scheduled to report sooner. Rookies for the Houston Texans and Kansas City Chiefs, the participants in the NFL’s season-opening game scheduled for Sept. 10, are slated to report Monday, at which point they would undergo coronavirus testing.

“We are all trying to get to the right decision far more than we are trying to get to a fast decision,” Smith said.

Other unresolved issues include the length of the preseason, the structure of training camps and economic considerations related to the salary cap and a potential drop in revenue. On testing, Smith said the NFLPA has been adamant about players being tested daily. The league has preferred for players to be tested every other day.

“They have pushed back hard on daily testing,” Smith said. “But one of the reasons that we have been such proponents of daily testing is going back to something that JC said earlier: Anybody can start the season, but I believe daily testing increases our chances for finishing.”
