Thursday, the Raiders canceled practice media availability for practice. The air quality has gotten extremely bad recently due to the wildfires raging across Northern California. Last Sunday the air quality at game time was around 170 which is deemed “unhealthy” by Air Quality Index standards, but not to the level that would keep the game from going forward on schedule.
Once it reached 200, the air quality jumps from “Unhealthy” to “Very unhealthy” which is the level at which the game would not be played. As of 11am the air quality was at 192. That was enough to have the practice moved to a walk-thru inside to limit the amount of inhalation of the air by the players.
