And then there were four.

Well, technically 28, as the semifinals in all seven classes of Iowa high school football have now been formed.

Johnston was one of those, as the No. 1 team in the state is one step closer to securing the first football title in program history. The Dragons are in the final four in Class 5A along with defending state champion Dowling Catholic, four-time champion Southeast Polk and Ankeny.

Reigning Class 4A champion Cedar Rapids and Sergeant Bluff-Luton comprise half of the final four there and are both in the Top-5 once again this week. Aplington-Parkersburg and Woodbury Central also advanced to the semifinals in their respective classes and moved into the Top-25 this week.

The High School On SI Iowa Top 25 includes all 11-player teams from Class A up to 5A.
