A teen athlete from New Jersey collapsed and died during football practice Monday evening.

Sean Fisher's mother was making cupcakes for his 13th birthday when the Waldwick teen was stricken at practice, she told The Record.

Sean, an offensive lineman, was in the middle of a drill with his teammates when he fell to the ground at the 33-yard line around 6:45 p.m., the newspaper reported Tuesday.

A father watching the practice, who is an EMT, immediately administered CPR. Paramedics arrived shortly after and used a defibrillator to try and revive him.

Sean, who was scheduled to begin eighth grade, was pronounced dead at Valley Hospital in Ridgewood.

The cause of death is not known.

School is scheduled to open next week, but counselors are available at the high school.
