The team announced Headrick's death. The Kansas City Star reported on its Web site that Headrick died of cancer. Chiefs officials had no details, including where the former TCU star lived or where he died.

Headrick played eight seasons for the Texans/Chiefs franchise. He was selected to five all-AFL squads and started at middle linebacker during the team's AFL title wins in 1962 and 1966, as well as the first Super Bowl.

Nicknamed "Psycho" by his teammates for his aggressive play and personality, he was inducted into the Chiefs Hall of Fame in 1993.

The Waco, Texas, native also played one season in Canada.
