Hall of Fame running back John Henry Johnson, who starred for the 49ers, Lions, Steelers and Oilers during his professional football career, died Friday. Johnson, 81, had been in declining health, according to family members. Johnson was inducted into the Pro Football Hall of Fame in 1987. "I speak on behalf of all of John Henry's fellow Hall of Famers, our Board and staff, in sending our condolences to the Johnson family," Steve Perry, the Hall of Fame's president and executive director said in a statement. "John Henry's place in football history as one of the game's most punishing runners and greatest blockers will forever be remembered through his bronze bust in the Hall of Fame."
