Calif. high school football player collapses, dies after practice

ALAMEDA, Calif. -- A 15-year-old high school student collapsed after football practice and later died at a Northern California hospital, officials said.

CBS San Francisco station KPIX reported that the student was at preseason football practice at Encinal High School on Tuesday, according to Alameda Fire Department spokesman Juan Medrano.

The East Bay Times identified the teenager as Giovanni Pulido. Team captain Makel Hale told San Francisco television station KGO-TV that the team was waiting to go home after working out in high temperatures, which were in the 80s, when Pulido collapsed.

Principal Kirsten Zazo said help was summoned immediately after it appeared the teenager was having a medical emergency.

The school district did not immediately disclose whether the players were practicing in full pads at the practice, CBS San Francisco reported.

Grief counselors and school administrators visited each of Pulido's classes Wednesday.

Officials say a cause of death will not be available for up to 12 weeks.
