Lyle Martin Alzado (April 3, 1949 – May 14, 1992) was a NFL American football player most famous for his intense and intimidating style of play.

Former NFL defensive linesman who played with the Cleveland Browns, Oakland Raiders and Denver Broncos from 1971 through to 1991. Alzado amassed a string of prestigious achievements in his NFL career including being named ABC's 1977 Defensive Player of The Year and Defensive Linesman of the Year, plus he was a key player in the Oakland Raider's Super Bowl victory over the Washington Redskins in 1983. He even flirted with the idea of becoming a professional boxer and fought eight rounds in an exhibition match with Muhammad Ali. At his peak, the fiery Alzado stood around 6' 3" and weighed in at approximately 255 pounds, however after a failed comeback attempt to the NFL in 1991, he admitted long term steroid abuse. His movie roles primarily consisted of Alzado playing tough guys, enforcers or similar hard cases such as in _Ernest Goes To Camp (1987)_, Destroyer (1988), Shocktroop (1989) and Comrades in Arms (1991). Whilst no conclusive link was ever established, Alzado was sure that his steroid abuse caused the brain tumor that eventually took his life. He passed away aged only 43 on May 14th, 1992 at his home in Portland, Oregon.
