A day before all NFL players are expected to report to training camp, the Minnesota Vikings have announced that Eric Sugarman — who serves as the team’s head athletic trainer, vice president of sports medicine, and infection control officer — tested positive for Covid-19.
Sugarman, along with members of his family who also tested positive, are experiencing mild symptoms and are self-quarantining.
The Vikings say the team is following its protocol for sanitizing the facilities and notifying any personnel who may have been in close contact with Sugarman. Those individuals have been tested and will return under established guidelines. Sugarman had not had any recent contact with players, and no additional Covid-19 cases have been identified among team personnel at this time.
In a statement, Sugarman wrote, “As I sit here in quarantine, it is clear this virus does not discriminate. It should continue to be taken seriously. I encourage people to take the necessary precautions and follow guidelines that have been established nationally and locally.”

The National Collegiate Athletic Association will allow schools to reduce their fall sports schedules to half of a typical season. The new waiver would not apply to football.
In a statement issued on Monday, the collegiate governing body revealed the waiver will be made available for men’s and women’s cross country, men’s and women’s soccer, field hockey, men’s water polo and women’s volleyball teams.
Those in conferences that have “eliminated” non-conference matchups for the upcoming season can continue to play while avoiding to schedule additional games. The change aims to limit travel and exposure to all parties involved amid the Covid-19 pandemic.
The NCAA’s oversight committee also suspended the criteria that required teams to have “at least a .500 record” to receive at-large bids into a championship field due to this new mandate.

President Trump said he hasn’t seen national security adviser Robert O'Brien recently, and he doesn’t know when his national security adviser first tested positive for Covid-19.
“I haven’t seen him lately,” Trump told reporters before departing the White House for North Carolina Monday afternoon. “I have not seen him, I’m calling him later,” he added.
Trump responded “I don’t know” when asked by a reported when O’Brien first tested positive.
Some background: As CNN previously reported, O'Brien's diagnosis marks the highest-ranking Trump administration official known to have tested positive. It's unclear when O'Brien last met with Trump.
Their last public appearance together was over two weeks ago during a visit to US Southern Command in Miami on July 10.
O'Brien is experiencing "mild symptoms" and is "self-isolating and working from a secure location off site," according to an unnamed statement to the press from the White House.
That statement confirmed O'Brien's test results to reporters before his staff was formally informed. Several National Security Council staffers told CNN that they weren't informed that O'Brien tested positive and learned of the news from media reports.
O'Brien, one of Trump's top aides, recently returned from Europe, where he and his top deputy met with officials from the UK, France, Germany and Italy.
A senior administration official told CNN that O'Brien has been working from home since last week. A source familiar said O'Brien was last in the office last Thursday, when he abruptly left the White House.
The White House statement said there is "no risk of exposure to the President or the Vice President."

New Jersey continues to report Covid-19 outbreaks from gatherings of young people, the state's Health Commissioner, Judy Persichilli, said during a briefing Monday.
At least 35 new cases of Covid-19 have been reported in Long Beach Island linked to what Persichilli described as a "common social gathering" of lifeguards.
At least 65 new cases of Covid-19 have been reported in Middletown over the past seven days, 52 of which are in people between the ages of 15 and 19, Gov. Phil Murphy said.
More on this: CNN reported last week that a house party in Middletown on July 11 may have been responsible for at least 20 cases of Covid-19 and that more cases were being reported.
Murphy didn't specify if all of those 52 cases were people who were at the Middletown party, but he did say that the parents of the teens who attended said party are cooperating with contact tracers and that the state now has the names of 59 of the attendees from the party.
"We're begging you to please be responsible at your home if you've got a gathering," Murphy said. "Don't congregate indoors."
New Jersey recorded 446 new cases of Covid-19 on Monday and 17 new fatalities, the governor said. The daily positivity rate in the state was 1.72%.
Murphy also reiterated that the state hopes to allow for at least some aspect of in-person learning for children in the fall. The state has released an education plan to allow for schools to reopen, but Murphy stressed that final decisions would be driven by public health indicators.
Note: The numbers listed were released by the New Jersey Governor's office and may not line up exactly in real time with CNN’s database drawn from Johns Hopkins University and the Covid Tracking Project.
