ALAMEDA, Calif. — The Raiders are still planning to host the Los Angeles Chargers in Oakland on Sunday despite concerns about poor air quality resulting from wildfires in California’s wine country.

The team said Friday that officials will continue to monitor the air quality in the Bay Area and would update fans if there were changes regarding the game.

Thick smoke and ash have filled Bay Area skies since the wildfires started Sunday about 50 miles north of Oakland. The fires have killed 31 people and destroyed at least 3,500 homes and businesses.

The NFL has been monitoring the air quality, which forced the Raiders to alter their outdoor schedule this week and raised the possibility that the game would be moved.

“I think we’re going to be fine,” Raiders coach Jack Del Rio said. “Obviously it’s a serious situation what’s going on up north. A lot of people have had their lives turned upside down. Some people have lost their lives so it’s a tough deal.”

Del Rio said that the conditions near the team’s facilities have improved over the past two days. Even so, the Raiders have advised players on precautionary steps to take, including the use of masks while outside.

League spokesman Joe Lockhart had said previously that because of the logistics involved in moving the game, a decision would most likely come Friday. Lockhart also noted that no decision had been made regarding the Raiders’ home game next Thursday against Kansas City.

“Historically when we need to move to an alternative site, we can’t wait until the day before,” Lockhart said. “I think the primary factor here is air quality. If we believe the air quality is at a level that playing the game would not be in the best interest or the safety of our players, we would move the game.
