The New England Patriots' training facility has been shut down again amid reports of a new coronavirus case, putting their Week 5 game against the Denver Broncos in doubt.
Patriots cornerback Stephon Gilmore had reportedly tested positive for COVID-19 on Wednesday, becoming the team's second high-profile case after Cam Newton.
Quarterback Newton had missed the Week 4 trip to the Kansas City Chiefs, with that game pushed back a day as a result of isolated cases for both teams.
New England - who lost 26-10 to the Chiefs - had been able to return to the practice field on Saturday, having received no further positive results up to that point.
"One thing that we've learned this year repeatedly has been we have to be ready to adjust and adapt to changes and modifications in the way we do things and in some cases decisions that really come down to a very short amount of time that we have to be ready to adjust to," Pats head coach Bill Belichick told the team's website.
"We're certainly taking things day by day, probably hour by hour would be more accurate."
However, on Sunday the facility was once again closed following the discovery of a fresh case, according to NFL reporters Adam Schefter and Field Yates. New England are said to be undergoing further tests while awaiting guidance from the NFL.
They are due to host the Broncos at Gillette Stadium on Monday, though the latest development makes it unclear if that game will go ahead as planned.
