Kluwe, well known for his support for gay rights and various political causes, turned his attention to Guy -- a six-time all-pro for the Oakland Raiders in the 1970s -- during Sunday's Vikings victory over the Chicago Bears by wearing a message on his uniform.
Kluwe stuck a Post-It Note over the Hall of Fame patch on his uniform bearing the message "Vote Ray Guy" as electors cast their ballots in the run-up to the Feb. 3 announcements, Yahoo! Sports reported.
The Vikings punter said Guy, who is on the 2013 ballot as a seniors nominee, has been snubbed because he was a punter -- no one from that position is in the Hall of Fame.
"He is the most well-known punter to ever play the game of football," Kluwe told the St. Paul Pioneer Press. "If you're going to have a Hall of Fame and you don't have the most famous guy at his position, what's the point?"
