Current head athletic trainer Jerry Weber said Sullivan died Tuesday.
Sullivan was regarded as a pioneer in athletic training practices and was inducted into the National Athletic Trainers Association Hall of Fame in 1976. Memorial Stadium’s athletic training room is named for him.
He retired from full-time work in 1994 and continued as a consultant to the athletic department and other organizations.
Sullivan grew up in Rockville and served in the Army in Germany and France during World War II. He studied physical education and physical therapy and played football at Nebraska upon his discharge. He was hired full-time as an athletic trainer in 1953 and treated players on national championship football teams coached by Bob Devaney and Tom Osborne.
