John McVay, the executive who helped launch the San Francisco 49ers dynasty and grandfather of Los Angeles Rams coach Sean McVay, has died. He was 91.
The 49ers announced Tuesday that McVay had died. They did not give a cause of death.
McVay spent 22 seasons with the 49ers starting in 1979 in various capacities. He played an integral role along with coach Bill Walsh in building one of the league's greatest dynasties that won five Super Bowl titles in a span of 14 seasons.
