Kyle was in critical condition since the beginning of his stay at hospital. TMZ reports that doctors have now declared that the young boy is brain dead. Sources say that Kyle didn’t have any brain activity since he was admitted to the medical centre Saturday.

It is unknown whether or not the family has decided to take the young man off life support.

Kyle is believed to have been sitting on an inner tube towed by a speedboat with a 15-year-old girl when the accident happened on Saturday. A passing jet ski struck him in the head.

Georgia Department of Natural Resources officials are investigating the incident.

Despite Usher’s bitter split from Tameka, the singer chartered a plane for her to be by her son’s side. Tameka – who was out of town at the time - was reportedly “extremely thankful” for the kind gesture.

Tameka split from Usher in 2009 and the pair are currently embroiled in a bitter custody battle over their two young sons.
