With a win Thursday night, Hilton Head Island High would have cemented a Class 3-A Lower State playoff spot.
But after a 51-32 loss at the hands of Berkeley, the Seahawks (5-5, 2-3 Region 8-AAA) find themselves waiting.
The game was competitive throughout the first half, and the Seahawks trailed 24-16 at the intermission.
But Hilton Head High went three-and-out to open the second half and the game began to slip away.
Never miss a local story.
"They scored and it just kind of steamrolled from there," Seahawks coach B.J. Payne said.
After the Stags took a 31-16 lead, the Seahawks drove back inside the Berkeley 10 but were held to a field goal.
After that, Hilton Head High had no answer for Berkeley's big plays.
"We just couldn't get a stop," Payne said.
Khalil Lewis had a big game for the Seahawks, rushing 27 times for 222 yards and a touchdown.
But Michael Julian had a shaky night, completing just 10 of 22 passes for 135 yards and a 55-yard touchdown to James Sanders. He also threw two costly picks.
Because of the S.C. High School League's new at-large system, Hilton Head High won't know its playoff fate until 9 a.m. Saturday.
Three teams from Region 8-AAA get berths. The Seahawks are the fourth seed. Depending on the outcomes of tonight's games, Hilton Head High could be selected for an at-large bid.
"We'll have to see," said Payne, who plans to be in Columbia on Saturday when the at-large bids are announced.
