With the air quality levels having risen to the very unhealthy range in the Berkeley area and a significant amount of smoke having infiltrated Haas Pavilion, Thursday night's men's basketball game between Cal and Detroit Mercy has been cancelled.In addition, given that the Air Quality Index (AQI) in Berkeley surpassed 200 Thursday afternoon, all Cal Athletics outdoor team practices were moved indoors with modified workouts or were cancelled due to health and safety concerns.No firm decision has been made regarding Saturday's Big Game between Cal and Stanford. Cal is continuing to monitor air quality, including reviewing data provided by the Bay Area Air Quality Management District (BAAQMD) and staying in regular communication with officials from Pac-12 and Stanford.Cal is following guidelines established by the NCAA Sports Science Institute and the Pac-12 Health and Well Being Board . The AQI can fluctuate as conditions change, and Cal will defer a decision whether to play the game once it has more data that would reflect conditions on Saturday.Officials from Cal Athletics, Detroit Mercy and the GotPrint.com Legends Classic presented by Old Trapper are discussing options to possibly reschedule the men's basketball game originally set for tonight.
