Central Florida wide receiver died Tuesday after voluntary strength and conditioning drills, the day before spring practice was set to begin. Police said there was no foul play or obvious cause for redshirt freshman Ereck Plancher's late morning collapse. UCF athletic director Keith Tribble said the players had been lifting weights, then ran for about 10 minutes. After they huddled and broke, Plancher, of Naples, took a knee in obvious distress, Tribble said. UCF trainers on site immediately provided CPR and the redshirt freshman was taken by ambulance to the hospital. He was pronounced dead just before noon.
