Long, who had been in a hospice for several months, died from a heart attack earlier this week with his wife Dorothy at his side, the university said Thursday. The couple lived in suburban Northridge.
Long played football at Oregon State, earning three letters as a guard before graduating in 1950. He coached five years in high school, then spent six years as an assistant at Willamette University in Salem, Ore.
In 1961, Long became an assistant at Oregon State under Tommy Prothro. Three years later, the Beavers won the AAWU to earn a berth in the Rose Bowl.
In 1965, Long joined Prothro's staff at UCLA and the Bruins went on to beat Michigan State in the Rose Bowl.
Long spent 11 years as a UCLA assistant under Prothro, Pepper Rodgers and Dick Vermeil, and in 1975, his last season, he worked with assistant Terry Donahue on the offensive line. The Bruins won the Pac-8 title and defeated Ohio State in the Rose Bowl that season.
Long worked more than a decade in athletic administration at UCLA, retiring in 1990.
Services will be Monday in Westlake Village.
