John McVay, an executive with the San Francisco 49ers who played a key role in building the franchise’s dynasty four decades ago, died Tuesday at age 91.

McVay joined the 49ers in 1979 and spent 22 seasons with the franchise, holding various jobs including general manager and director of football operations.

Under his direction, the 49ers won five Super Bowl titles in a 14-season span and McVay was named The Sporting News NFL Executive of the Year in 1989 after the team’s fourth Super Bowl championship.

The 49ers inducted McVay into the team Hall of Fame in 2013 and dedicated the draft room at the team’s headquarters in his honour in 2016.

''This is a very sad day for our organization and the entire football community,'' the team said in a statement. ''John McVay was a driving force in constructing teams for our five Super Bowl titles.

"Most importantly, John was a Hall of Fame person who built genuine and sincere relationships with front office staff, coaches and players. John's commitment and contributions to the 49ers created the standard and tradition we strive to carry on today. Our thoughts and prayers are with the McVay family.''

McVay is the grandfather of current Rams coach Sean McVay.
