George Darlington, the longest-serving assistant coach in Nebraska football history and a staff member on three national championship teams coached by Tom Osborne, dies at age 87, the Nebraska athletic department says. The department announces his death but does not disclose a cause. Darlington spent decades with the program and remained closely involved even in recent years as his health declined. Sources describe him as a regular presence at practices and a fixture in the Nebraska press box on game days. His tenure included periods under Osborne and later under Frank Solich, reflecting his long association with the Cornhuskers’ coaching staff. Across the reports, Darlington is characterized as a long-time figure within the program who supported the team’s operations and game-day preparation for generations of players. The news of his passing is noted alongside recognition of his record-setting duration as an assistant coach at Nebraska and his role in multiple championship seasons.
