Kahuku’s Stennett Alapa, an offensive lineman, hurt his arm in Saturday’s 35-7 loss to Bishop Gorman on Saturday.
He is expected to miss the rest of the season, Hawaii Prep World sources said.
Alapa, a senior, was an integral part of the Red Raiders’ O-line.
Calls to Red Raiders head coach Vavae Tata for comment were not returned.
Kahuku was on an 18-game winning streak until the loss to the Gaels (4-0), the top-ranked team in the nation. Kahuku, ranked 17th in the USA Today Xcellent 25 at the time of the game, is now No. 24.
It was Tata’s first loss as Kahuku’s head coach. His first 13 wins came last season en route to the Division I state championship. The Red Raiders (5-1 5-0 Oahu Interscholastic Association Blue) have not lost a game to a Hawaii team since his arrival.
Kahuku, the top-ranked team in Hawaii, finishes its regular season with two away games — at Moanalua (3-3, 2-3) on Saturday and at Kaiser (2-5, 1-5) on Sept. 30.
