A 14-year-old Somerset County boy collapsed and died during gym class at his high school, according to school officials.

Authorities say the Franklin High School freshman collapsed on the football field around 9:10 a.m. Tuesday. School staff performed CPR before the boy was taken to a hospital, where he was pronounced dead a short time later.

“We are providing counseling to our staff and students. Our thoughts and prayers go out to the student’s family at this time,” a spokeswoman for the district said in a statement.

The boy's name hasn't been released. Officials haven't said what activities students were doing when the boy collapsed.

The cause of death remains under investigation.
