A 94-year-old physician who served as team doctor for five U.S. men's Olympic hockey squads has suffered serious injuries in an attack while visiting his wife's grave.

KMSP-TV reports George Nagobads was mugged Sunday afternoon at the Crystal Lake Cemetery and left bleeding from the head. A witness says Nagobads managed to get back in his car and drive away. The unidentified witness says he saw a young man looking through a wallet near the mausoleum before fleeing.

Nagobads was the University of Minnesota men's hockey team physician for 34 years until his retirement in 1992. He also worked for the Minnesota North Stars in the late 1980s and early 1990s. And he was team doctor for the famous "Miracle on Ice" team that won Olympic gold in 1980.
