A highly anticipated O'ahu Interscholastic Association showdown and a Division I vs. DII matchup of ranked teams highlight this weekend's football action.

Farrington, ranked No. 5 in The Advertiser's statewide Top 10 poll of coaches and media, travels to No. 7 Kahuku tonight with sole possession of first place in the OIA's Red Conference Eastern Division on the line.

Kickoff is set for 7:30, and the game will be televised live statewide on OC16.

In the Interscholastic League of Honolulu, No. 1-ranked Saint Louis takes on No. 9 'Iolani tomorrow at Aloha Stadium. Both teams are unbeaten in league play, but this will be 'Iolani's first game against an ILH Division I team.

Here is a closer look at both games, plus three other OIA Red Conference matchups with playoff seeding implications:

FARRINGTON AT KAHUKU

Farrington also had to rally in the fourth quarter to win its last game, a 17-14 triumph over then-winless Kailua.
