Oregon and Oregon State are monitoring hazardous air quality in the area as both schools prepare to host football games Saturday.
Wildfires in the state have brought smoke and ash to the Willamette Valley region, causing Oregon to cancel a cross-country event scheduled for Thursday. Oregon hosts Nebraska on Saturday afternoon, and Oregon State hosts Minnesota later that night.
The Pac-12 in a statement said it remains in communications with athletic officials and medical staff at both schools, as well as the regional protection agency, to determine if the air quality is good enough to have the events take place as scheduled, or modify the kickoff times or even the date of the games.
