Alex Karras, an All-Pro defensive tackle for the Detroit Lions who later worked as a "Monday Night Football" co-host and parlayed his hulking strength into a Hollywood acting career, died Wednesday. He was 77.
Karras died at his Los Angeles home, his attorney Craig Mitnick said. Karras had suffered kidney failure days earlier, the latest in a variety of health problems that included dementia and cancer.
He was one of more than 3,500 former NFL players who are suing the league in a dispute over concussion-related injuries.
