Hall of Famer Steve “Mongo” McMichael, a key figure in the Chicago Bears’ legendary “46 defense” of the 1980s and the franchise’s second all-time leader in sacks with 92.5, has died at the age of 67, the NFL announced Wednesday per ESPN.

McMichael had been battling ALS, also known as Lou Gehrig’s disease, since his diagnosis in 2021. He was set to enter hospice care on the day of his passing.

The legend (October 17, 1957 – April 23, 2025) was a formidable presence in both professional football and wrestling, renowned for his tenacity and larger-than-life persona. Born in Houston, Texas, McMichael excelled at the University of Texas, earning unanimous All-American honors and setting school records for tackles and sacks. ​

Drafted by the New England Patriots in 1980, McMichael found his stride with the Chicago Bears, joining them in 1981. As a defensive tackle, he became a cornerstone of the Bears’ dominant defense, contributing to their Super Bowl XX victory in 1986. Known for his durability, he played in a franchise-record 191 consecutive games and amassed 95 sacks over his 15-season NFL career.

After retiring from football, McMichael transitioned to professional wrestling, joining World Championship Wrestling (WCW) in 1995. He became a member of the famed Four Horsemen stable and captured the WCW United States Heavyweight Championship in 1997. ​

In 2021, McMichael publicly revealed his diagnosis with amyotrophic lateral sclerosis (ALS). Despite the progression of the disease, he remained a symbol of resilience, receiving the Les Turner ALS Foundation’s Courage Award. His contributions to football were honored with his induction into the Pro Football Hall of Fame in 2024. ​
