"After experiencing flu-like symptoms, Denver Broncos linebacker Von Miller has tested positive for COVID-19," the team said.
"Von has elected to share his diagnosis publicly to emphasize that anyone can be afflicted with coronavirus."
"Von is doing well and recovering at home in self-isolation. He remains under the care of team doctors, who are following all coronavirus treatment procedures to ensure a safe environment for Von and our community.
"Von is the first member of the Broncos' organization known to have tested positive for COVID-19."
NFL superstar Von Miller -- one of the biggest stars in the league -- has tested positive for the coronavirus, his agent says.
Unclear when the 31-year-old Denver Broncos pass rusher was diagnosed but his agent Joby Branion tells NFL Network's Ian Rapoport he's "at home resting and in good spirits."
Miller -- the MVP of Super Bowl 50 -- is expected to speak publicly on Friday.
Miller's announcement comes one day after L.A. Rams center Brian Allen revealed that he was also diagnosed with COVID-19.
Allen said he became concerned once he lost his sense of smell and taste. He is also on the mend.
The NFL has made adjustments in the wake of the pandemic -- choosing to hold a virtual NFL Draft next weekend, where players, coaches and execs will all participate from home.
Miller's diagnosis, once again, proves even the healthiest people on Earth are vulnerable to COVID-19 ... after it already struck other top athletes including Kevin Durant, Donovan Mitchell, Rudy Gobert and others.
Miller is a stud on the field -- he's an 8-time NFL Pro Bowler, 3-time All-Pro and is currently in the middle of a 6-year, $114 million contract.
