A star high school football player died after he collapsed while running laps on the track.

Brian Bell, 17, was pronounced dead on arrival Tuesday night at Parkway Regional Medical Center.

He was working out with the football team, having just finished lifting weights and running laps at Monsignor Edward Pace High School, officials said.

A school trainer performed CPR and Bell still had a pulse when he was taken to the hospital, said Joe Zaccheo, the school's athletic director and football coach.

"Nobody knows what brought it on," Zaccheo said. "They had just started the running phase of their conditioning. It was a very light thing. As a matter of fact, he had just rested about five or 10 minutes."

Bell, a 6-foot, 185-pound defensive back, was a first-team All-Dade County selection last season. He also wrestled at the school and would have been a senior this fall.

"This is probably the best athlete on the team," Zaccheo said. "I'm talking condition-wise. He probably would have gone to a Division I school.

"You had a lot of schools interested in him. This was a young man who had everything going in the right direction. He was doing all the right things: working a job, keeping his grades up."
