Denver Broncos star Von Miller said he considered opting out of the 2020 NFL season due to coronavirus concerns.

Miller – a Super Bowl champion and eight-time Pro Bowler – was among the highest profile American athletes to test positive for COVID-19 in April before being cleared of coronavirus two weeks later.

However, the Broncos linebacker revealed he thought about sitting out the season, which is scheduled to begin in September.

"I thought about it,'' the 31-year-old said on Tuesday. " ... I thought about all of my family, I took serious consideration and the things that could possibly happen.

"It's not a 100 per cent bubble like basketball, so there are always going to be holes, but I felt like the job the Broncos were doing to keep us safe was enough for me not to opt out.''

Miller, an asthma sufferer, added: "I did [have trouble], it was hard for me to get my wind back, probably for two or three weeks after the virus.

"During the virus I lost a lot of weight -- everybody is not the same, but for me I lost my taste and smell, I couldn't really, like, eat and when you can't taste or smell you kind of lose your appetite ... It was tough, no doubt about it, it was tough.''

"I just thought about it, I just really through about all the things that could possibly happen,'' Miller continued. "I thought about this season is different, I thought about -- I weighed the positives and negatives and just came to my own decision that I could play.

"But I thought about me having asthma ... I feel like every player should do that, I feel like every player should think about everything they could do.''

The Broncos are set to open their season against the Tennessee Titans on September 14.
