The starting running back for a playoff-bound western Pennsylvania high school team has died days after suffering a stroke while watching a game between two other teams.

Kyle Wilson, a junior at Central Catholic in Pittsburgh, had been unconscious and in critical condition at UPMC-Children's Hospital since he collapsed while attending another game on Thursday.

Central Catholic coach Terry Totten says Wilson suffered a stroke not related to football and had practiced normally with the team last week.

A deputy says the Allegheny County Medical Examiner's Office is not investigating the death because it involves natural causes.

Central Catholic, the defending PIAA District 7 Class AAAA champions, meet Penn-Trafford in a first-round playoff game Friday night in Fox Chapel.

Totten told the Pittsburgh Post-Gazette Thursday that the team is struggling with the loss.

"The kids have very heavy hearts, to say the least," Totten said. "But they'll get through practice. I think they're committed to honoring him by practicing and ultimately playing. It's been tough, though. There's no playbook for this, you know?"
