Navy freshman slotback Will McKamey died Tuesday, three days after collapsing during a football practice, the Naval Academy said in a release late Tuesday night.

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."
