Smoke from nearby wildfires has caused unhealthy air quality throughout much of Western Montana (MTN Sports photo).

Changing air conditions continue to affect the high school football schedule.

Hazardous air quality postponed or moved every football game scheduled for Friday night in northwestern Montana. Drummond-Philipsburg hosted Alberton-Superior in the state’s western-most game Friday.

Saturday is seeing more movement on the schedule.

Frenchtown and Libby have now canceled their Class A football game. The two teams, originally scheduled to play Friday, had settled on a postponed matchup on Saturday in Fairfield. Conditions worsened in Fairfield Friday night and Saturday morning, though, so Frenchtown and Libby will not play.

An 8-Man South tilt between Hobson-Moore-Judith Gap and Ennis has also been postponed. The game was slated for Saturday afternoon in Moore, but the teams will now meet Monday in Hobson. Kickoff is scheduled for 5 p.m.

There is some good news, though. The air quality at Hamilton and Corvallis has improved enough for those schools to host their games against Browning and Polson, respectively. Both games were previously considered to be moved to Naranche Stadium at Butte, which hosted Great Falls High and Missoula Sentinel on Friday, but will now kick off Saturday at 4 p.m. at their home sites.
