NEW BRUNSWICK, N.J. (CBSNewYork/AP) — The only horse ever to be penalized in a college football game has died.

Lord Nelson was euthanized on Sunday when he couldn’t get up after falling on the ground, said Karyn Malinowski, director of the Rutgers Equine Science Center.

He was 42, or the human equivalent of 126 years.

One of Lord Nelson’s duties during his 37-year Rutgers career was carrying the school’s Scarlet Knight mascot during football games. It was against Army in 1994 that Lord Nelson was penalized for unsportsmanlike conduct when he broke free and raced down the sideline at Giants Stadium.
