Poor air quality due to wildfire smoke from Canada has forced Thursday's Major League Soccer game between the Vancouver Whitecaps and Fire at Chicago's Soldier Field, along with a scheduled postgame concert, to be postponed.
The game, which was expected to draw 40,000, will be made up on Oct. 6.
Heavy, pungent wildfire smoke darkened skies in the U.S. from the Great Lakes to parts of the East Coast, reducing visibility and prompting warnings that breathing the air outside could be dangerous.
Officials in many cities urged residents to stay inside or wear masks outside as air quality reached unhealthy to hazardous levels, meaning it's unhealthy for anyone, regardless of health conditions. The National Weather Service said a lingering high pressure system has trapped the smoke close to the ground.
Trinity Rodman, a member of the United States women's national team, said the smokey sky was difficult to deal with during Wednesday night's NWSL game between the Washington Spirit and Gotham FC at New York's Citi Field.
Rodman said she wasn't a fan of the hydration breaks every 15 minutes in the game as the temperature reached into the 90s.
"Air quality was rough," Rodman was quoted as saying by The Athletic. "Not to make excuses at all, but I think on both sides we were all like, 'another break, another break, another break.'"
A crowd of more than 42,000 attended the rematch of teams in last season's NWSL title game. The crowd was a record for a women's sporting event in New York City.
"If we have to have a hydration break every 15 minutes, then we shouldn't be playing the game, and that's my opinion," Rodman said. "But at the end of the day, there's 40,000 people. It's a whole event, so it's really tough. It's just a really hard situation for everyone to work around."
