Glover, the 11-year-old son of Usher's ex-wife Tameka Foster, has not experienced any brain activity in the past two days since being admitted to the hospital. He was reportedly struck in the head by a passing jet ski while inner tubing on Lake Lanier in Atlanta.

According to the Atlanta Journal-Constitution, officials have ruled out alcohol as a factor and have recognized that the man on the jet ski and Glover were part of the same group. The cause of the incident is still under investigation.

Usher and Foster were married in 2007 and had two children together, Usher Raymond V, 4, and Naviyd, 3, before getting divorced in 2009.
