Jim Marshall, the ironman who set the Vikings' gold standard for toughness and leadership while never missing a game in the franchise's first 20 seasons, did not make the list of finalists for the Pro Football Hall of Fame's 20-member Centennial Class.

The Hall on Wednesday released the list of 20 senior candidates, 10 contributors and eight coaches who will be considered by the special Blue Ribbon committee. That committee will then select 10 seniors, three contributors and two coaches. The other five members of the Class of 2020 will be modern-era players chosen by the 48-member selection committee on the eve of Super Bowl LIV in Miami.

The Vikings have made strong pushes to get Marshall into the Hall of Fame for years, but they stepped up efforts this year in hopes that the expanded field would include the man that Hall of Fame coach Bud Grant considers the cornerstone of a franchise that's in its 59th season.

Marshall's only year as a Hall of Fame finalist was in 2004. He played for the Vikings from 1961 to 1979 after playing in the CFL in 1959 and with the Browns as a fourth-round draft pick in 1960.

Marshall played 282 straight games, a record that only Brett Favre ended up breaking among position players.

Of the 38 finalists presented to the Blue Ribbon committee, running back Roger Craig is the only one with ties to the Vikings. He played the final two years of his career with the Vikings in 1992-93.

Here are all the finalists that will be considered by the Blue Ribbon committee:
