A Jefferson County high school basketball standout died Thursday afternoon.

Pinson Valley High School senior Caleb White suffered a medical emergency at school. Life-saving efforts were started at the school, and White was transported to the hospital where he was pronounced dead.

The incident happened in the late morning.

Principal Michael Turner announced the student’s death in a note sent to parents which was later shared with the media.

Turner said counseling would be available to students and staff in the coming days.

White’s grandfather, George Varnadoe Jr., posted on Facebook that his 17-year-old grandson collapsed while working out with the team.

“Caleb was an honor student, very respectful, high intellect, excellent role model, phenomenal basketball player, ranked 25th best point guard in his class in the nation and No. 2 in the state of Alabama.”

“RIP Caleb,’’ Varnadoe wrote. “I love you man.”

The 5-foot-11 White was one of three finalists for Class 6A player of the year as a junior and was a first-team all-state selection. He averaged 20.9 points, 3.8 rebounds, 3.1 assists and 1.9 steals for the Indians.

As a sophomore, he averaged 17.3 points, 3.3 rebounds, 2.1 assists and also had 71 steals.

“Heartbroken,’’ Pinson Mayor Joe Cochran posted on Facebook. “No words can be gathered to provide comfort to a family and community experience the loss of young life.”

“I was honored to know Caleb personally and loved the spirit he carried,’’ Cochran wrote. “Life is fleeting. Enjoy every day as the treasure it is. I know Caleb did.”

Pinson Valley basketball coach Darrell Barber could not immediately be reached for comment. Social media tributes poured in from basketball coaches and programs across the state.
