Former San Francisco 49ers tackle Keith Fahnhorst passed away on Tuesday, June 12 at the age of 66.

Fahnhorst originally entered the NFL as a second-round (35th overall) draft choice by the 49ers in the 1974 NFL Draft. He spent all 14 of his NFL seasons with San Francisco (1974-87), appearing in 193 games (160 starts), the second-most among 49ers offensive linemen (Len Rohde) and the eighth-most regular season appearances in franchise history. He also started all 10 postseason contests that he appeared in.

A two-time All-Pro (1983-84) and 1985 Pro Bowl selection, Fahnhorst was part of two Super Bowl Championship teams (XVI & XIX). He was also a two-time recipient (1981, 1986) of the 49ers Bobb McKittrick Award, which is given annually to the 49ers offensive lineman who best represents the courage, intensity and sacrifice displayed by the longtime offensive line coach, during his 21 years of service to the 49ers.
