"We are all so very heartbroken by the death of Midshipman Will McKamey," Naval Academy Superintendent VADM 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."
McKamey never regained consciousness after undergoing surgery to relieve bleeding and swelling in his brain, according to the Baltimore Sun.
McKamey also collapsed on the field during a 2012 game when he was in high school in Tennessee and airlifted to a hospital. He did not have surgery but the episode ended his senior season. He did not play in 2013, but was cleared to resume playing football after seeing four neurosurgeons, according to a statement released by his family Monday.
"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," the family said in a statement.
"Our deepest and most sincere condolences go out to their entire family and friends," Navy coach Ken Niumatalolo said. "As our Navy football family mourns the loss of one of our brothers, we also celebrate and honor his life. He loved his family, his friends and his teammates. The Brotherhood loves you. Keep the ball high and tight in Heaven."
