A second-round pick of the 49ers in 1974, Fahnhorst spent the entirety of his 14-year NFL career in the Bay Area. During that time, he emerged as a key bookend along San Francisco's offensive line and played a role in keeping Joe Montana upright throughout the team's fruitful run in the 1980s.
Fahnhorst started 160 of the 193 regular-season games he appeared in between 1974-1987. His peak came in 1984, when he was rewarded for his efforts with Pro Bowl and first team All-Pro honors.
On June 4, the 49ers announced legendary wide receiver and Fahnhorst's former teammate, Dwight Clark, died at the age of 61.
