McKamey -- a 19-year-old freshman from Knoxville, Tenn. -- fell into a coma Saturday and was airlifted to the University of Maryland Shock Trauma Center in Baltimore, where he underwent surgery for a brain clot. The Navy said McKamey had his family at his bedside.
"We are all so very heartbroken by the death of Midshipman Will McKamey," Naval Academy Superintendent Mike Miller said in a statement. "This is devastating news for his family, his classmates, his teammates and the entire Naval Academy family. We offer our deepest condolences to Will's family, friends and shipmates in the wake of this tragedy."
The family issued a statement earlier this week, saying that McKamey "did not sustain a bad hit or unusual or extreme contact in practice Saturday. The Navy coaches have poured through the films of practice and seen nothing more than Will carrying the football normally, doing what he truly loves."
McKamey collapsed on the field in a game during his senior year of high school. He was treated at a hospital but did not undergo surgery. McKamey did not return that season, but was named Mr. Football in Tennessee in 2012.
The family said McKamey had been examined by four different neurosurgeons after the 2012 incident and was cleared to play.
