Mike Webster, American football player (b. 1952)
Michael Lewis Webster (March 18, 1952 – September 24, 2002) was an American professional football player who was a center in the National Football League (NFL) from 1974 to 1990 with the Pittsburgh Steelers and Kansas City Chiefs. He is a member of the Pro Football Hall of Fame, class of 1997. Nicknamed "Iron Mike", Webster anchored the Steelers' offensive line during much of their run of four Super Bowl victories from 1974 to 1979 and is considered by many the greatest center in NFL history.Webster died in 2002 at the age of 50 of a heart attack, and subsequently was the first former NFL player diagnosed with chronic traumatic encephalopathy (CTE). Since his death, he has become a symbol for head injuries in the NFL and the ongoing debate over player safety. His doctors were of the opinion that multiple concussions during his career damaged his frontal lobe, which caused cognitive dysfunction.
