Authorities say a 16-year-old high school football player who died after collapsing during a game suffered bleeding on his brain, apparently from a helmet-to-helmet collision.

Cortland County Coroner Kevin Sharp says Ridge Barden died from a massive subdural hematoma, a traumatic brain injury.

The lineman for John C. Birdlebough High School in the Oswego County village of Phoenix was hurt during Friday night's game at Homer High School, south of Syracuse. Authorities say he was able to sit up after the play but complained of a headache and collapsed when he tried to stand.

Sharp says there's no evidence of any pre-existing injury or condition that contributed to Barden's death.

He says the fatal injury was consistent with the helmet-to-helmet hit reported between Barden and another player.
