Stone Johnson

Stone Edward Johnson (April 26, 1940 — September 8, 1963) was an Olympic sprinter and American football kick returner and running back for the Kansas City Chiefs.
On August 30, 1963, the rookie Johnson, a 200 meter track finalist in the 1960 Summer Olympics in Rome and former world record holder, suffered a fractured vertebra in his neck in a preseason game against the Houston Oilers in Wichita, Kansas during a kickoff return. He died 10 days later, on September 8 at the age of 23. Although he was only on the team's active roster during preseason, his jersey number 33 was retired.
