Fan who attended Texans-Chiefs NFL opener tests positive for COVID-19

How can they positively attribute this to attending the game? All research shows it's HIGHLY unlikely to get a positive result one day after exposure.

I get the bigger picture (unknowing asymptomatic public spreading) but this article reads like they are attributing his positive to being at the game, which seems very untrue. and paints sports attendance in a bad light.
Don't think they're saying he got it from the game.
They’re not. NFLN specifically stated they weren’t claiming that, at all. Instead, the emphasis is being put on contact tracing...anyone that fan came in contact with at the game, and in the parking lot. They also noted that tailgating was allowed for that game.
