Jason Ray, a senior from Concord, N.C., was to have performed inside the Rameses costume during Friday night's East Regional semifinal between the Tar Heels and Southern California. He was injured while walking in the afternoon in Fort Lee, N.J., a few miles from the Meadowlands complex where the game was played.
Ray was taken to Hackensack Medical Center, the school said. His parents were en route to the hospital.
"We are deeply saddened by this tragic accident," North Carolina athletic director Dick Baddour said. "Our hearts go out to Jason and his family and our prayers are with them."
