Kyle Glover was involved in a jet ski accident in Georgia earlier in the month and later declared brain dead.
Doctors have since removed Glover from life support after concluding that his injuries were too severe to recover from, TMZ reports.
Glover's mother Tameka Foster is said to have "struggled tremendously" with the decision and is "understandably devastated".
It was previously reported that Foster couldn't afford her son's hospital bills and would therefore have to remove her son from life support when her insurance company stops paying for his care.
A family friend is thought to have lost control of his jet ski and collided with Glover on Lake Lanier. The accident is currently under investigation.
