It was late in the fourth quarter on the first Friday of September, and the game was close.
The Dassel-Cokato high school defense dug in on the line of scrimmage against Orono when suddenly, instead of setting himself for the play, linebacker Luke Nelson turned and staggered away.
Chargers coach Ryan Weinandt didn't wait for a whistle. He bolted onto the field and rushed to the 16-year-old junior, helping him sit down.
"I'm hurtin'," Nelson said, slurring his words.
From the home-side bleachers, Luke's parents, Sara and Greg Nelson, saw their son rolled onto his side and figured he was vomiting. Then one of his legs suddenly straightened. Instinctively, they knew: He was in seizure.
Within 10 minutes, Nelson was loaded into an ambulance for the 15-mile trip west from Cokato to Meeker Memorial Hospital in Litchfield. Greg, a member of the Dassel Volunteer Fire Department, rode with his son.
No one knew for certain at the time, but Luke was bleeding on the brain, most likely from a hit during the game, and in danger of dying.
Concussions and head injuries have become the scourge of American football from the pro ranks through youth leagues. The effects range from players filing multimillion-dollar lawsuits claiming long-term brain damage to parents increasingly keeping their children from playing for fear of injuries like Luke's.
