A 17-year-old football player in Georgia was found dead on Sunday, a day before he was supposed to represent his high school in the state championship game, authorities said.

“We are heartbroken to hear the news of the tragic and untimely death of one of our student-athletes, Brandon Smith,” the Meriwether County School System said in a statement.
