From penitentiary to pugilism, “Big” Ron Lyle remains one of the most menacing heavyweights the sport has ever seen. Never a champion, yet a hard night’s work for every great fighter who laced up the gloves against him. He turned professional at 30 and finally walked away for good at 54. His life was as punishing and dramatic as any fight he ever had.
Ron Lyle was born Ronald David Lyle on February 12, 1941 in Dayton, Ohio, the third of 19 children born to William and Nellie Lyle. In 1954 the family relocated to Denver, Colorado, where his father worked at Buckley Air Force Base and also served as a part time minister. The Lyles lived in housing projects on the northeast side of Denver. Ron grew up in the Whittier neighborhood and fell in with street gangs. After being told by his basketball coach at Manual High School that he would not make the team, he dropped out at 17.
At 19, Lyle was involved in a gang confrontation that ended with the shooting death of 21 year old Douglas Byrd. Lyle maintained he was being attacked with a lead pipe and did not pull the trigger, yet he was convicted of second degree murder and sentenced to 15 to 25 years at the Colorado State Penitentiary in Canon City.
Prison nearly killed him. He was stabbed by another inmate and underwent a seven hour operation. Twice pronounced dead on the table, he required more than 30 blood transfusions to survive. During a 90 day stay in solitary confinement, Lyle began rebuilding himself through exercise. Push ups, sit ups, squats. Discipline replaced chaos.
A prison boxing card on July 4, 1962 changed everything. Watching from the crowd, Lyle told himself he could do better. By 1964 he made his boxing debut behind bars. He credited Lt. Cliff Mattax, the prison athletic director, with believing in him when few others did. Lyle once brushed him off, saying a guard and a convict could never connect. After surviving the stabbing, he reconsidered. Mattax saw potential. Lyle chose to live up to it.
He excelled in multiple sports in prison, coaching the Wildcats football team to an inter prison championship and playing baseball and basketball. In the ring he lost his first bout to Texas Johnson. He never lost another prison fight. He had roughly 25 amateur fights while incarcerated, losing only once and winning six inmate heavyweight titles.
Parole boards initially rejected his plan to pursue boxing. Then Denver businessman Bill Daniels offered him a job as a welder and an opportunity with the Denver Rocks boxing team. Lyle was paroled in November 1969 after serving seven and a half years. The next morning he reported to the gym.
His amateur career lasted just 14 months, but it was decorated. He won the 1970 National AAU Heavyweight Championship, the North American Amateur title, and the International Boxing League championship. He fought on the United States Boxing Team, knocking out Kamo Saroyan on national television.
Turning professional at age 30 under Daniels and trainer Bobby Lewis, Lyle wasted no time. He won his debut by second round knockout and stormed to a 19 and 0 record with 17 knockouts. He flattened Vicente Rondon, Buster Mathis, and Larry Middleton, and defeated former champion Jimmy Ellis. He was ranked among the top heavyweights in the world.
His first major setback came against veteran Jerry Quarry, who outboxed him over the distance. Losses to Jimmy Young followed. Still, Lyle remained a feared puncher who could change a fight with one shot.
On May 16, 1975, he challenged champion Muhammad Ali. Lyle started aggressively and was ahead on all three scorecards entering the 11th round. Ali, calculating and patient, seized his moment. A crushing right hand and a flurry forced the referee to stop the fight. Lyle’s corner protested, but the opportunity slipped away.
If the Ali bout showed his competitiveness, his 1976 war with George Foreman defined his legend. In one of the most savage heavyweight battles ever staged, Lyle went straight at the former champion. He rocked Foreman with thunderous punches and knocked him down twice in the fourth round while hitting the canvas himself. Along with Ali and Jimmy Young, Lyle is one of the few men ever to floor Foreman as a professional. Foreman rallied to stop Lyle in the fifth, later calling him the toughest and hardest hitter he ever faced. The bout was named Fight of the Year by The Ring magazine.
Lyle also defeated Oscar Bonavena, Earnie Shavers, Joe Bugner, Gregorio Peralta, Jose Luis Garcia, and Scott LeDoux. Shavers, himself a feared puncher, said no one hit him harder. Foreman ranked Lyle among the three hardest punchers of his career alongside Gerry Cooney and Cleveland Williams.
The end of the 1970s brought decline. Draws with fringe contenders and a shocking one punch loss to Lynn Ball signaled erosion. A first round knockout defeat to the rising and undefeated Gerry Cooney at age 39 led to retirement.
Outside the ring, trouble revisited him. In 1977 a man who had known him from prison was shot and killed in Lyle’s home. Charged with first degree homicide, Lyle claimed self defense and was acquitted in 1978.
In 1995, inspired by Foreman’s improbable title winning comeback, Lyle returned at age 54. He scored four quick knockouts against modest opposition and sought a rematch with Foreman. The fight never materialized. He retired for the final time.
He never held the heavyweight crown. Yet he stood toe to toe with legends and never asked for mercy. From a prison cell to center ring under bright lights, Ron Lyle forged redemption with his fists. In doing so, he became one of the most feared and unforgettable punchers of his era.
In later years, Lyle ran the Denver Red Shield gym and mentored young fighters, including future champion Victor Ortiz during part of his amateur career.
Ron Lyle died on November 26, 2011 in Denver, Colorado at age 70.
