The final four in Nassau I kick off the semifinal round of football playoffs this weekend. Two backyard rivalries, loaded with history, go down Thursday night in Hofstra’s Shuart Stadium.

Top-seeded Farmingdale, ranked No. 1 in the Newsday Large Schools poll, will put its 9-0 record on the line against Massa pequa at 4 p.m.

The Chiefs (7-2) gave Farmingdale quite the scare during the regular season. Farmingdale avoided defeat when kicker Briant DeFelice drilled a last-second 34-yard field goal for a 45-42 win on Oct. 8.

The Dalers win behind quarterback Tom Donovan and halfback Jordan McLune, who has 1,137 yards rushing and 25 touchdowns. Massapequa survived a thriller against Oceanside and came away with a 31-28 win.

Also in Nassau I, Freeport (8-1) will meet Baldwin (6-3) at 7:30 p.m. Thursday. These programs have a 90-year rivalry and this game features two of Nassau’s top scorers. Freeport pounded Baldwin, 37-7, in Week 3 but the Bruins are so much better than the team that took the field early in the season.

Bruins halfback Johnathan DeBique has 1,144 yards rushing and 14 touchdowns. And Freeport leads all of Long Island with 376 points behind quarterback Rashad Tucker, who has nine touchdowns and Elyjah Campbell, who has 17 scores.
