Prep football kicked off Friday night with two clutch victories for Robertson and West Las Vegas.
The Cardinals, ranked as high as No. 1 in Class 4A preseason polls, won a marquee matchup with Class 3A's top team, defending state champion Estancia, 27-26.
In doing so, Robertson snapped the visiting Bears' 17-game winning streak that dated back to October 2014. The Bears went 13-0 last fall.
Up north in Clayton, the Dons scored twice in the second half after a 0-0 deadlock in the first half hour of game time, holding on for a 14-8 win.
