His family said he had been cleared to resume playing football after seeing four neurosurgeons and undergoing several CAT scans and MRI exams.
The 5-foot-9, 170-pound McKamey did not play in a game last season. He was an oceanography major in 3rd Company at the Naval Academy.
"During this most difficult of times, first and foremost, our prayers and thoughts turn to Randy, Kara and their beautiful family," Navy coach Ken Niumatalolo said. "Our deepest and most sincere condolences go out to their entire family and friends. 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."
Navy said funeral arrangements are pending.
