Pat Fischer, a feisty and fearsome if diminutive defensive back who played 17 seasons in the National Football League, including the final 10 with Washington, died Oct. 8 in Ashburn, Va., after suffering from dementia.

Pat Fischer, the two-time All-Pro cornerback who spent nearly two decades in the NFL, has died at the age of 84. A spokesperson for the Washington Commanders confirmed his passing in a statement to The Associated Press.

"Fischer was one of the greatest defensive backs in franchise history," The Commanders said Tuesday. Fischer was 84.
