There is certainly no shortage of prep football this weekend.

Twenty-three games will be played out on four islands over the next two days. The load is especially heavy Friday night with 15 contests, including several league games that will determine who sits in first place — for the time being, anyway.

Kaiser visits Radford in a pivotal Oahu Interscholastic Association White Conference game, while Waianae will host Mililani in a Red West battle.

Meanwhile, over in the Interscholastic League of Honolulu, the second- and third-ranked teams in the ScoringLive/OC16 Division I Power Rankings — Kamehameha and Saint Louis, respectively — will face off in the feature game of a doubleheader at Hawaiian Airlines Field at Aloha Stadium in the UHA Game of the Week.
