The family of 5-year-old Ian Freeman released a statement on Saturday through the Arnold Palmer Hospital for Children that he passed away Friday night.
The incident happened earlier in September during a privately run program at Lake Brantley High School.
Authorities said during diving practice, Ian fell 9 feet from the 3-meter platform onto the pool deck below.
According to school officials, Freeman was on the high-dive alone and away from the water when he suddenly slipped.
He was airlifted to Arnold Palmer Hospital.
In the statement the family said they were "extremely humbled by the outpouring of support."
They have set up a fund to honor Ian, and those wishing to contribute can call 407-719-0079 for more information.
The family did not provide any information on funeral services, but did write they will "celebrate Ian’s life with the community at an appropriate time." Until then, they asked for privacy.
The boy was on a team that is run by the Patriot Aquatic Program, which rents the pool from the high school, according to officials with Seminole County Public Schools.
WFTV learned the child's mother was at the pool when the accident happened.
The accident happened in front of coaches, lifeguards, parents and other teammates.
